Just recently got this project running, so I might as well do a writeup.

Here goes.

Intake mani and TB's

First, get some 01' or higher Suzuki GSXR 1000 or 750 Throttle Bodies.

Then get an extra intake mani.

Cut the runners off approximately 6" from the head flange.

Go to Home Depot and get some rubber plumbing couplers. They're about $5 a piece with clamps.

Clamp the Mani and TB's together to yield this...

http://img.photobucket.com/albums/v607/ScooterS14/ITBs/top3.jpg

http://img.photobucket.com/albums/v607/ScooterS14/ITBs/bottom1.jpg

http://img.photobucket.com/albums/v607/ScooterS14/ITBs/megasquirt019.jpg

And with the couplers trimmed down, and the velocity stacks on...

http://img.photobucket.com/albums/v607/ScooterS14/ITBs/ITBs.jpg

http://img.photobucket.com/albums/v607/ScooterS14/ITBs/ITBs005.jpg

Now make 2 brackets that brace the TB's to the mani, for extra strength.

I used 3/4" by 3/16" steel. You can find this at Home Depot. Bolted one end to the TB's and the other slips under the mounting point for the PCV rail. Make one per side. Should look something like this...

http://img.photobucket.com/albums/v607/ScooterS14/ITBs/megasquirt023.jpg

Now make a bracket for the throttle cable to slip into. I used 1 1/2" angle iron. This can also be found at Home Depot. Make it to bolt onto the mounting surface that the EGR used to sit on.

http://img.photobucket.com/albums/v607/ScooterS14/ITBs/megasquirt017.jpg

http://img.photobucket.com/albums/v607/ScooterS14/ITBs/megasquirt018.jpg

Get a SOHC throttle cable. The DOHC one is wayyyy too long. The SOHC cable is too long too, but better than the DOHC one. The end of the Nissan throttle cable that slips onto the throttle wheel fits in the Suzuki throttle wheel perfectly.

get two air boxes from a 01' and up GSXR 750. These have the shortest velocity stacks. Each airbox has two short stacks, and two long ones. Once you have 2 boxes, you will have two full sets of velocity stacks to help you achieve the best powerband down the road.

http://img.photobucket.com/albums/v607/ScooterS14/ITBs/stacks001.jpg

That's it for the manifold part of things.

Now the fuel management.

I chose to use a MegaSquirt (MS) because of price, and because, well, I love DIY stuff as you can probably see. haha

Get your board and bags of components all lined up like so...

http://img.photobucket.com/albums/v607/ScooterS14/MegaSquirt/megasquirt004.jpg

Build the stimulator first. This will help you learn how to make proper solder joints befor you start soldering the actual MS together. The stimulator hooks up to Megasquirt and stimulates the MS such that it thinks it is running an engine. What this does is allow you to make sure all of your MS is built and running correctly before trying to start the car with it. It also allows you to download new codes to the CPU chip as you see fit, without having to have the MS in the car. Very trick.

http://img.photobucket.com/albums/v607/ScooterS14/MegaSquirt/megastim005.jpg

Follow the MegaManual at www.megasquirt.info and you will end up with this...

http://img.photobucket.com/albums/v607/ScooterS14/MegaSquirt/wheels2007.jpg

Now build the pigtail for the wiring harness...

http://img.photobucket.com/albums/v607/ScooterS14/MegaSquirt/harness001.jpg

and here's a better pic of how many wires there are. This is the entire engine harness. Stock one gets removed completely.

http://img.photobucket.com/albums/v607/ScooterS14/MegaSquirt/harness002.jpg

that's basically it for the MS.

Now for the ignition setup.

I chose to run a distributorless system off of early 90's Ford Escorts. This system uses a trigger wheel that is mounted to the crank pulley to fire the ignition instead of a gear driven distributor. This has many advantages, the first of which being that it is more accurate than the stock distributor. It also gives full control of the ignition timing.

from left to righ in the pic below, we have the EDIS module, the VR sensor (reads the trigger wheel on the crank pulley) and the Coil.

http://img.photobucket.com/albums/v607/ScooterS14/ITBs/megasquirt015.jpg

Here is a picture of the spark plug wires modified to fit down the spark plug holes in the valve cover. the boot that connects to the plugs has about a 30 degree bend in them so I bent them back straight, and trimmed the boots until they slid down into the holes in the valve cover.

http://img.photobucket.com/albums/v607/ScooterS14/ITBs/megasquirt014.jpg

Next, you have to get a trigger wheel made. I have a friend who is a CNC machinist, so he made one for me, as well as prepping the crank pulley for the wheel.

http://img.photobucket.com/albums/v607/ScooterS14/MegaSquirt/megasquirt024.jpg

And the wheel fit onto the pulley looks like so...

http://i7.photobucket.com/albums/y263/scooters142/itbs010.jpg

http://i7.photobucket.com/albums/y263/scooters142/itbs008.jpg

Now make a bracket to mount the VR sensor onto. I put mine where the A/C compressor used to be. just some more of the angle Iron used before, long enough to mount the sensor on, facing the crank pulley.

Next, make a block off plate for the hole that the distributor used to occupy. I made mine big enough to mount the new coil to, as that is as far as the plug wires would reach. Just simple 1/8" thick steel. when finished it looks like this bolted to the engine, with the new coil mounted on it.

http://i7.photobucket.com/albums/y263/scooters142/ITBs004.jpg

http://i7.photobucket.com/albums/y263/scooters142/ITBs003.jpg

On a side note, here is the stock KA24DE timing map I scaled down. I have used it and it works great.

http://img.photobucket.com/albums/v607/ScooterS14/MegaSquirt/stocktimingmap.jpg

Putting it all together.

Now pull off your stock intake mani, and take out your engine harness. You will no longer need either of these. bolt the new mani onto the engine, it should look something like this...

http://img.photobucket.com/albums/v607/ScooterS14/ITBs/itbs005.jpg

http://img.photobucket.com/albums/v607/ScooterS14/ITBs/itbs002.jpg

http://i7.photobucket.com/albums/y263/scooters142/ITBs001.jpg

http://i7.photobucket.com/albums/y263/scooters142/ITBs002.jpg

http://i7.photobucket.com/albums/y263/scooters142/ITBs005.jpg

You can also see in those pics the wiring harness was finished. It's simply following the diagram, running each wire to each sensor.

the only things that were not on the diagrams were the tach signal, water temp gauge and the switched ignition power supply. the Tach signal was cake, run a wire from the Clean Tach Out pin on the EDIS module to the Tach input on the back of the gauge cluster. That's it. Speedo will still work. Run a wire from the second temp sensor in the intake mani to the coolant temp input on the back of the gauge cluster. that's all for that. And the B/R wire coming from the igntion switch on the steering column needs to be tapped into to get switched power to MS, and the ignition components.



However, the wiring diagram for the ignition is slightly off. the polarity of the VR sensor wires is opposite than in the diagrams, so wire that up accordingly.

I used the stock injectors for now, but I have some SR injectors lying around waiting to go in. Stock injectors will be enough for now.

for the brake booster, I used the stock PCV rail, and ran one line from its output to the brake booster. Has worked great. I also Tee'd a 1/4" vacuum line out of this line, on it's way to the booster, for the fuel pressure regulator. Before doing any of this, I measured the vacuum in this line, and in the rest of the intake mani under all braking conditions, and the booster did not affect the vacuum in the engine. This being so, it is safe, and fine to run the vacuum for the FPR from the brake booster vacuum line.

the TB's come from the factory with a vacuum line from each port Tee'd into one. this is used for the map sensor. Simply run a line from this to MS. the MAP sensor is inside the MS box.

Then swap out the throttle cables, and hook the SOHC one up.

Finally, plug the EGR hole in your header.

If I recall correctly, this is about it for what I did on this whole project to get it running. for the specifics of the MS building and whatnot, and the ignition specifics and diagrams, visit www.msefi.com and www.megasquirt.info.

I specifically did not go into extensive detail in these areas because it is covered very well at those two sites.

So finally start it up and get it idling correctly. Do this by adjusting the screw that adjusts how far open the throttle plates are at "closed" so it has an idle speed you like, and adjusting the fuel amount in the MS. You can then get your own wideband to tune it, or take it to someone. Wichever's clever.

After tuning it, GO DRIVE IT! Don't forget to give yourself a pat on the back too!

Please forgive me if I have forgotten anything, it is a very long project, there is so much to do. I may have left a few small details out, but this is the major stuff.

Driving impressions
I don't have it tuned very well yet, but I can tell you that throttle response is immediate. The engine also revs up MUCH quicker. It does not feel like the lunky old KA. It's a whole new engine. This definately made it come alive. It is, of course MUCh louder also. It no longer sounds like a KA. Sounds way more pissed, like an engine with 2x the displacement.No dyno slips yet, but once I get one, I will be certain to post it up, as well as a video/soundclip.

Cheers

There's some reading material to keep you guys busy. hahaha And I might have another smaller write-up soon here if/when I build another manifold setup.

I did get it dyno'd. Peak #'s aren't that high, but look at the torque curve, and lack of significant top end hp falloff. With cams It's going to be a whole new beast (for maeda to make fun of). hahaha

http://i7.photobucket.com/albums/y263/scooters142/dyno001.jpg

Rough cost was ~930 for the ITB's, MS, and all the other junk that goes along with it.

I'm selling my current ITB setup, as I'm making a new one. So if you are interested (seriously), PM me. I'll put them up in the FS section in a couple weeks.

Companies that make cams for KADE's:

JWT
Gude
PDM Racing
Crower (used to, can do custom grinds too)
And some more I'm sure. But none reputable I can think of...

A note on valvesprings and retainers. It's been confirmed that CA and KADE valvesprings and retainers are the same. You can use CA springs and retainers in your DE. I was talking to a very reputable source that said that CA and VG springs and retainers are the same. So if this is true, for valvesprings and retainers CA = KA = VG. This means lots of choices.

I'm getting some cams (JWT) in the next week or two for my engine. I should have before and after tests on the same dyno with the cams. I'll also play with velocity stack length before and after, to help get a better idea of ideal runner length for the two different sets of cams.

Oh and SOHC pistons in a DE. I havn't tried it out yet, but It is more likely than not that aftermarket cams in a DE with stock sohc pistons will not work together. Will put the valves into the tops of the pistons. The valve reliefs in the sohc pistons do not line up with the valves in the DE. I've run this across a few reputable nissan engine builders, and they also highly doubt that cams with much higher lift than stock will work with stock sohc pistons.

And because people alway ask...

The highest hp N/A KA24DE to date puts down 365 flywheel hp. I forget the torque. 290rwhp. I want to say 25x rwtq, but don't quote me on that. This engine is used in the Nismo baja truck things. They see 11,500rpms in the air. You can buy them with a few hours on them now and then for a pretty penny. Call BS if you want, I've talked to the builder myself.

for those serious ppl, a friend of mine has a gt3 motor up for sale... if anyone is serious please pm me. CR 13:1.. i believe its setup for a v band style belt.. so either your going to have to fab up ur own pulley or youd have to by one... the motor is setup for dry sump already... this is all thru WOM from a friend...

12-09-2005, 06:54 PM
I also wanted to add that since the KA doesn't have a fully counter weighed or knife edged crank that there are affordable alternatives.
Did some research on crank scrapers found that this company makes them for the KA... http://crank-scrapers.com/prod01.html
Some people can look at them and think that they are worthless, but it is to break windage in the crank case, and increase HP. I am not going to say that it is any type of significant HP, but for $50 and a 3HP gain at peak I wouldn't mind having one. Especially since people have claimed that it increases rev as well.
If ecu tuning and ITB's isn't your thing,(although I do plan to do it in the future) you can just have the TB bored, and ported from www.maxbore.com.
RBS14 mentioned a diverse amount of cams available, I believe the im Wolfe is the best streetable cam on the market(although it cost the most)
Great write up RBS13.

I am planning on building the KA and staying n/a. I am shooting to go past 200hp, however I was curious on something. How much can the stock ka24de cams hold? Should they be upgraded right away or should I save it towards the end? If so, what cams are reccomended?

RBS14
05-03-2006, 08:22 PM
they suck. Get rid of them. What cams you get depends on the powerband you want. Easiest is JWT.

RBS14
05-08-2006, 06:34 PM
there's 95% of the power curve (everything but WOT) that there is no quantitative way of representing. Not to mention response. Instant power! that's where the ITB's really shine. It's just one of those things you have to do to appreciate. Just a dyno chart won't convince you. With cams I got about 170 to the wheels with real tuning (timing). But now it's boosted so it's a whole new game.

im pretty sure those baja truck if they are the same as what they run at crandon brush run (20miles from me) they are fuel injected. when you hear and see them do what they do in real life its amazeing, they beat up on the v8 classed trucks alot of the time in the shoot out. the v8's are in the 800hp+ range, bu they are are bigger and heavier. the one we got to see looked fuel injected but it looks nothing like a 240 ka.

06-11-2006, 10:02 PM
ok i got a question ... how high of a compression can i go on pump gas on a ka24de ... i was think of a shorter rerouted intake, port n polish, headers cams, 2.5 pipes, jwt ecu, and higher compression if possible for n/a build ???

ranisron
06-12-2006, 07:16 AM
most high comp pistons for the DE is the 10.5 to 1 ratio. However, the E pistons can bump the compression all the way to 11 to 1 (correct me if I am wrong).

10.5 to 1 will run on pump gas no problem, and getting your ECU retuned for high comp application is recommended.

anything above 11:1 is unsafe for the KA (I think).

bouncin_180
06-12-2006, 02:06 PM
whats stock compression for a DE ... and where would i be able to get high comp pistons ... mostly i just find the low comp ones ...

tre
06-12-2006, 05:03 PM
You can walk into any piston maker and they've probably already made high comp pistons for the DE.

If you're feeling good with your milling capabilites. You can pick up SOHC flat top pistons, mill in valve releifs and mill the piston to lower the compression to 11:1

irritatedmax
06-15-2006, 11:27 PM
the only company i have seen advertise high compression ka pistons is supertech. they have a 10.5:1 set that goes for around $400.

as far as cams go, i have seen people use s13 sohc cams in the de is that beneficial in this case or is jwt the way to go. what is the difference in the lift/duration? as you can tell, i have more questions than answers but i am looking to build an na ka for reliability over turbo/power. i know above 200whp is pretty much impossible but i would like to see someone hit it.

Posted this a while back with no response. Figured I'd put it in here this time with hopes of better luck. I was going to do my lifters soon in my 89 KA and I figured I might as well gain some HP since they're gonna take the cam out anyway. Do have an idea what kinda HP I might get with this cam on a stock motor? I asked Summit and they said "there are to many variables to determine such as what header, what intake, what injectors you are using". I told them it was a STOCK motor. How can I make it any more clear!!!!!!!!!!!!
The only thing I have is a cone filter in place of airbox and a 2.5 exhaust.
Here is link, hope you can give a general idea.

So what are your n/a ka24 et's?

I did a [email protected] with my 5spd 91' (i/h/e). This was done with an open diff with 3yr old 215/35/18's. I spun the whole 1st gear and over revved 1st to 4th gear (7800rpm/no rev limit/I don't know why) and had a super crappy 2.599 60ft. With an lsd and better driving I should easily do high 14's on street tires.

7800 rpms is kinda dangerous on the KA no?

I was waiting for the rev limiter to kick in, but it never did. On neutral the fuel cuts very smoothly at 7800 rpm (tried this only once), unlike my 2001 1.8 sentra which feels like the motor is gonna explode from the rev limiter, or my stock 240 tach is just broken.

doesn't make any sense either b/c the power curve decreases at higher RPMS.

ranisron
09-07-2006, 09:30 PM
7800 is wayyyyyyyyyy too high for a KA... the stock limit is below 7K...

I don't know... KA is a great motor for making torque, and it's definitely not a high rev motor...

TURBI
09-10-2006, 04:10 AM
So my tach must not be so accurate if the rev limiter should hit before 7000rpm. Also I don't feel any "ka falls flat on it's face after 6000rpm", my motor feels strong all the way to 6800rpm, maybe from the bolt-ons and shaved head.

Anyways, I still wish there was a bolt on centrifugal supercharger kit for the ka24de's. (at least 6psi):blah: :blah:

question, What about building an air box around the ITB's and then run a hose to or bolt the MAF on to the side of the air box? Then all you would need is something like the BIKI Rom setup and some dyno time and I think that would be a pretty good setup.

2nd question, Is the STOCK TB on the KADE actually 42mm? that seems very small to me. it looks more like 60mm. If it is 42mm, Isn't the KA-E 60mm? I know that is good upgrade for the VG30ET

a plenum for ITB's is a totally custom job. i had one made, but am no longer using it cause i went to standalone. the ITB's definately change the character of hte motor more then the peak power and teh sound is amazing.

PS: if anyone wants the plenum, email me

i know this is probably a stupid question, but i have no idea. are ITB's gonna decrease the life or dependability of your engine? will they last? any info would be great!

Maybe something like this would work. It's a fully built ka24de in a 72' 510 with mikuni side drafts and a t3/t4 turbo set up here on Saipan.

As for the ITB's, i'd love to have them but there is no way i can afford or even set up a stand alone fuel management. Ive seen a member from NICO do ITB's but had a plenum in order to use the maf. Ive tried contacting him, but he never responded. Does any one know where I can buy the plenum or instructions as to how to make one??

i just got a 89 240. its lacking power of course, yet i dont want to lose the n/a reliabilty. plus its my first car and my rents dont want me to have a turbo (so no sr) because it will be too fast of a first car. so im thinking about getting a 16 valve ka and swapping it with my 12 valve. then ill do basic bolt ons and ill be done. hoe does this sound?

OK... for some odd reason I have actually had people asking if the SR20Down pipe will fit the NA KA24DE!! I guess because its similar in design!!

The answer is NO... unless you have a KA-T w/ custom Turbo Ellbow.

I actuall went out and installed an RS*R DP, SARD Tourqu Control Valve, and Full Kakimoto Exhaust on my S14... the 3 bolts off the Main will line up and bolt corectly... the issue was with the slight angle difference, and the mounting plate from the DP to the Trany. The mount can be cut off but it doesn't change the angle.
After you install the cat or test pie you will see its sitting much closer to the ground... if you get as far back as the Rear subframe you will be about a foot lower and never make it to the mounts.

This was actually fun to play with the idea... car looked so dumb sitting with the rear end about 2 feet off the ground and a full exhaust sitting on the ground. I couldn't force myself to shame my car with pictures.

SR Down Pipes are for SR20s or CA18s only... maybe a KA-T!!

u are correct, in order to use a piggyback the maf has to be present.. but u also dont have to have a standalone for itbs. u can have a plenum made and still use the stock maf but if u want open itb's then be willin to pay out the big bucks for a standalone

You don't have to use a VR sensor with the MSEFI like the install I saw posted earlier. Just use the stock Opto CAS and use the falling side of the signal. Of course, if you're really paranoid about timing and plan on going with a MS2 I hear you can run both a 12-1 wheel off the crank and the opto off the Cam. Again, that's if you're paranoid about chain slack or maybe want to attempt Sequential Injection. Or if you don't want to play with the Opto you can do VR, nothing wrong with either install.

MSEFI ftw!

Some one did this on Altimas.net, and the result could have been better if he used quality parts.

He has to run super retarded ignition timing, and in a foolish move, bought the pistons on ebay.

With out a tune, it ran rough, it pinged, and who knows what else. He says he might try it out again.

248/248 is a pretty cool setup starting off. ive never seen 248/232, all s14 guys ive seen swap the cams put 2 s13 exhuast cams in and not leave the stock exhaust 232. jwt are like 270 duration right? anything bigger? if seen a lot of corolla guys with like a 300 duration cam. i wonder how that would idle? lol

using 248/248 is said to push the powerband too far up, are you sure you didn't mean 248/240?

PDM,and Crower make cams for the KA24DE as well, But I don't think anything (i've seen at least) tops JWT's 275/275. And there was no low end loss.

Hey guys i have a very quick question and i know it has been asked before so im not gonna post a new thread to talk about it....Is there any difference between a 92 KA block to a 96 KA Block (sensors and what not as in obdI to obdII)? I know the 98s are different cuz i understand they changed something related to the timing chain. Reason i ask is because i have a spare 92 KA engine in the garage and i want to rebuild it for my 96 s14 and just use the s14 head and sensors.

What ECU are you running?

Cuz I'm on almost the same setup as you (no pulley but 5spd). I want more power, but I want to maintain daily driver, so I was wondering what other bolt-ons/minor mods that I can put on (NOT EXHAUST, I don't want heat from the cops) to increase power a bit.

I'll tell you this, The dyno Proves what I said all along, stock cams blow Hard core on these cars. Even With Cams, I'd Estimate I'd be in the High 140's, low 150's (and thats with better weather, advandced Ignition timing, Proper gapped plugs) But the ehaust Would Offer Really nice gains on top of all I have. If You don't want to be Hounded By the cops, a 2.5 Catback is quieter, and Will offer similar gains.

I'm hoping With everything above, Plus a 3.0 Catback, I'll touch the 160whp mark. Which is just enough for me.

Btw, for those who asked.

I guess theres some kind of plenum thing in the intake manifold on the Ka-E that if you take out ads a few horses, but I dont actually know what it is, and I cant find anything anywhere about it and what it does. Only thing i found is that it slows the air down, but that doesnt make sense. Maybe i suck at searching. But if anyone knows what im talking about, id like to know. Even if it does add power i probably wont take it out, but its just bugging me i dont know.

infinitexsound
08-02-2007, 07:35 PM
what it is, is a secondary throttle . alot of cars have it mid way thru the intake manifold.. but on the sohc its mainly at the edge of the flange where its bolted down next to the head... takes a few minutes to take out... once u have the manifold off the head..just unscrew the plates off the rod, then slide the rod out... i highly suggest jb welding the holes and sanding it smooth... reason for this is for no vacuum leak...

you could do ITB's but it takes alot of fabrication and theyll probably run you at least $1000 not to mention the ecu mods for the it, if your lookin for a NA build for under $1000 id go with Brian Crower stage 3 cams (or stage 2 depending if its gonna be ur daily or weekend warrior) new BC springs and JWT ecu that should run about $1360 but the ECU should give you pretty good gains

efi specailist make custom ecu's for about 305 for all motor setup n turbo..im thinking about picking one up in a week or to.

Product Information
This upgrade is for 1991-1994 KA24DE running all motor setup. This will be a custom tune specific to different cams, high compression pistons, and headwork. The fuel and timing maps are remapped and optimize for all motor KA24DE. Speed limit is removed and the rev limit is raised. Intake, header, and exhaust are recommended for this setup.
Price: $305.00

sounds pretty good so im gonna give them a try n see how much better they are than jwt

o man hey what kinda power gains did you get with the JE 11:1 pistons cause i was thinking about getting those but i need to find some one to bore out the engine cause they only come oversized right? most impressive intake plenum, ive been looking for a good intake manifold but couldnt find one but this one looks pretty good. that ecu sounds good, do you have a link?

Can we get a mod to clean this shit up? and also:

Lets have a discussion on the formula for finding the right cam duration.
Is it better to have higher lift duration on the intake or exhaust side? Why?

I've heard preaching of the 240/248 but I've also heard the 248/232 is better.

Lets shed some light.

longer duration less lift, high compression..... doesnt leave alot of room for high lift cams.... plus the head design is pretty tight...as in clearance.... just get a stock cam and have elgin in santa rosa,ca or schneiders in so cal.... make some custom grinds and see what happens...

Everyone talks about the head being so restrictive on NA KAs. Has anyone considered trying to swap heads with other nissan four cylinder engines? I'm not sure if any of these would come close to fitting the KA without MAJOR work, but it's worth looking into at least. I googled but I couldn't find anything with the head "footprints" to be compared to the KA's "footprint". Hell, even head gaskets comparison might be enough to get a general idea. I may look more into this later today if I have more time.

If this idea is completely stupid, then please forgive me. Please note that NO I am not a machinist, NO I do NOT know how much work it would be to modify heads, so please don't lecture me on being ignorant, but please provide some sort of indication to the degree to which the heads do not match.

Some Nissan four cylinder heads that should be considered:

SR20DE
SR20VE (I've heard this head flows rediculously well)
FJ series
CA series
CG series
QR seies

Yes I'm aware that most of these heads probably flow much worse than the stock KA.

edit: Yes I realize that if a head does match and does flow better, then the next problem would be the timing chain, and cover, but one step at a time.

KA240SX808
03-01-2008, 01:17 AM
^From what I've read is that the KA head was the best flowing of it's time???? Not sure it;s true but there is a possibility.


Perhaps the Newer Frontier Heads were improved?

07-13-2008, 10:47 AM
^^^I would keep it. Others may say you can remove it. I'm not sure on nissans but other cars like hondas, the Evap purge kicks in on decel (55mph-15mph). Suprisingly in warmer climates quite a bit of fuel is evaporated if the EVAP isnt used, this container contraps it, and vacuums the vapors into the IM to be burned, which has 0 affect on performance- however more possible throttle response from sealing a port on the VC. You may notice a slight decrease in your MPG if removed.

If the car is tracked only, rip it out. Just my 02

I thought boring out the KA to 2.6 would drop the RPM revs to like 5500 instead of its 8000. You would get some nice torque but wouldn't this be useless for drift/track/ I only see this being used for 1/4 times and thats it. In which case I wouldn't bother.

sr 370cc injectors and a z32 TT pump, walbro or equivalent fuel pump is sufficient.

I'd like to add a larger maf to your list. this list of parts can go on and on but I feel you would get the most performance (without building the bottom) from cams, head work, matchporting everything, fuel system upgrade, ignition upgrade and of course, a well tuned ecu.

btw:
if you are OBD1, boring the tb a few mm is not as great of a performance increase as upgrading to a larger maf with matching intake/filter and a good ecu tune. Mind you the throttle body mounting pad may also need attention.

what maf would u suggest? i have a maxima n60 i was going to use with my turbo set up before i decided to build na :)...

i hear the jwt ecu is the best in the market.. that would work im assuming?

as for obd1 its a 96s14 im pretty sure thats obd2.. and ignition upgrade would just be some pulse plugs? what more could i do..? a dli would be overkill wouldnt it?

09-21-2009, 12:27 AM
If you are OBDII, then you probably have the G70 MAF and that should be fine for NA.

JWT ecu tunes are descent. I've been hearing good stuff with the nistune boards (OBD2 KA is a Type 4). This is what I'll be running in the near future.

Upgrading the ignition on a OBD2 KA is not very simple. With that said, just make sure you are getting the proper voltage to the distributor, iridium plugs and upgrade the ignition wires.

Quick question related to the KA wiring harness... I figured this would be a good spot to ask.

I stripped/de-pinned the extra harness I had. It's a 1995 KA24DE M/T harness.

WHen I went through the ECU pinout and F3 pinout to double-check what was cut and about to be removed, I ran into an issue..

ECU Pin #33 = Red/Yellow wire = Throttle Position Sensor SIGNAL
F3 Plug Pin #26 = Green/Orange wire = Throttle Position Sensor

Both of those wires ended up cut. I checked the TPS plug, and all 3 wires are intact and connect to the ECU as they should. TPS Power, Ground and Signal all connect to ECU.

I'm ASSUMING, those two wires are meant to connect together, and I'm prepared to solder them back together if needed, but I didn't think it made sense. Why would the ECU need to send a TPS signal to the F3 plug? What else would be communicating with the TPS?

Any ideas/help would be awesome! I want to get this thing shortened and tucked!

If it is the late OBDII model, it seems that there are 2 components you are questioning. 1 is the Throttle Position Sensor and the 2nd being the Throttle Position Switch.

True = ECU Pin #33 = Red/Yellow wire = Throttle Position Sensor SIGNAL (low voltage)

Flase = F3 Plug Pin #26 = Green/Orange wire = Throttle Position Sensor

True = F3 Plug Pin #26 = Green/Orange wire = "Closed Throttle Position Switch"
This component receives power from switched ON or START "BR" into pin "S18" on Connector F3. From Connector F3, "BR" may lead into a Y or may continue to pin "5" on the Closed Throttle Position Switch. From the Closed Throttle Position Switch pin "6", the wire should turn to color "L/G" straight into the ECM "F1' or main computer at pin "27".

^^ cool vid man! looks like lots of fun to me haha.. im omw there :)

lol okay so i have a timing question.. ive heard a buddy of mine talk of advanced timing.. and i belive ive read some on the forums about it.. how does it work? what does advancing the timing do exactly.. power curve? how far is it possible to go and is it possible to do in my garage?

is the nistune board type4 for the s14 a plug and play aplication?? or do i have to splice and dice to get it to work? haha...

I just read the 7 page, im new to the forum, I would like to know something. I have sr20 injectors and a 300zx maf in my garage that are doing nothing. I would like to install them with a ecu tune up. Do you think it will make a big difference, does somebody here did it? does I need to put other parts to be safe like a fuel pump or headgasket.... Thank for your help

project-D180
10-09-2009, 01:19 AM
i would use the fuel pump if you use the sr inj..headgasket i would mess with unless you doin a rebuild.you dont need sr or 300zx maf if your runnin a stock motor.maybe if you threw in 264 or 272 cams with some headers n exhaust,intake..but if you plan on runnin high comp pistons then i would use the sr inj with a good ecu tune 11.0.1 or more cr..10.5.1 i dont think your would really need them depending on your setup and what hp range your aimin for..i have stock injectors wit a walboro fuel pump wit my tuned ecu n its runnin fine for now but im bout 2 sell me ecu n probaly go with nis tune or enpathy so i can use 370 inj so i a make more power

What ECU are you running?

Cuz I'm on almost the same setup as you (no pulley but 5spd). I want more power, but I want to maintain daily driver, so I was wondering what other bolt-ons/minor mods that I can put on (NOT EXHAUST, I don't want heat from the cops) to increase power a bit.

My setup is similar to yours with the exception of Wiseco 9.0cr pistons. Oh and OBDII. Just purchased the NIStune Type 4 board and installed it with a close to oem tune. I'll play with the maps after the 370cc injectors go in.

I have another KA short block with 12.0:1cr bottom end sitting in the garage.

I have another KA short block with 12.0:1cr bottom end sitting in the garage.

~mario

I'm curious to see how well that would run

This is my friends set-up:
SOHC pistons
Cometic HG for 10.7:1 compression
248/248 Intake/Exhaust cams
Head port and polished with stock intake and z32 Ferrera valves (about 2mm bigger than stock)
both the block and head were deburred to remove hot spots
clevite rod cap bearings with ARP hardware
new OEM waterpump and oil pump gear
EGR capped
Swirl Control removed
Coolant to TB capped
RSR 3" Catback
New O2 and Temperature sensors
everything else stock, auto ECU

motor has excellent throttle response and is a blast to drive.
we took it to the dyno last night and frankly were a little disappointed
car feels faster than what the numbers state
we are, however, pleased with the shape of the powerband curve

http://img267.imageshack.us/img267/939/november172009dyno14587.jpg

Nistune and an ITB setup is in the works
also planned for the future when money and time allows are:
exhaust manifold
fuling
bigger MAF
bigger throttle body
bigger cams

the car is running too rich at the moment and we feel that just a good tune
alone would net us some more power.

1 thing i kno kills the ka power gain is our gay ass stock intake mani thats y i went with the xcessive one.its not so restrictive

12-01-2009, 11:48 PM
This seem to be the right spot to ask... I have been looking around zilvia to find if there was a combination of head and block I should use to gain power.. I've heard from some guys that you could put a (91-94) Head on a (95+) block and get high compression from that..

I'm just looking for some input.. on gaining more N/A power

project-D180
12-03-2009, 12:54 AM
if it was that damn easy we would have all ben doin it.i believe the 95-98 head flow better than the 91-94,now if you build a high comp motor from there then you should be golden but tuning it is goin 2 play a big role in that and modifing the intake mani

Iceman00
12-29-2009, 11:41 PM
Wow it has been a while, I see not any huge progress has been made..
A few points:

Off the shelf headers will probably suck. If you want real power, look into a Burns collector or some Kromer Kraft headers/

Stock/factory cams are shit. You can advance and retard them all you want, but a good set of cams will go a long way

Tuning is a huge part of the pie. There is a reason that I was able to match a lot of these guys number with Just an intake, header and ECU tune. No cams, Stock exhaust. JWT may be mild, but it was a step in the right direction.


Now carry on...

Doesn't the Dynopack Rate at the Hubs, and Not the wheels?
Anyhow, Like I said, Completely Stock Cat, and 1.75" Exhaust, and Automatic Trans. Not to mention the Rediculous heavy 50lb Wheel and tire combo (Sentra SE-R wheels).

Im gathering up the bits and peices of my next rebuild, and really dont have many options for high compression pistons, and my cam selection is also very limited to what im willing to use. This is my what my build will consist of.

Rebuilt KA24E, tuned for E85 on an AEM EMS
-arias 10.8 compression pistons,
-nismo R4 cam,
-OBX header, 3" apexi n1 exhaust
-Ebay $9 intake w/ k+n filter
-Lightweight fidanza flywheel
-Lightweight driveshaft

My queston is, if I use the arias 10.8 or 10.7 compression pistons will I be able to use the Nismo R4 cam and not have any issues with piston to valve clearence?

Dosent sounds like much of a build but im also going to be running this motor with E85, and tunning it with an AEM ems so im hoping to hit around that infamous 200whp mark.

02-07-2010, 12:52 PM
they sould have valve relief built into the piston for added inssurance..they should clear though..you would have 2 check the clearance when u get them or jus askin the company your buyin them from

put clay in the cylinder, bolt the head on, turn the engine with a breaker bar ... check clay for valve clearance

smbonn2005
02-15-2010, 07:21 PM
Don't quote me on this but I'm pretty sure just plain old modelling clay would work fine. Just make sure you clean the valves/pistons/combustion chamber afterwards just in case of any residue left over

Yeah they have some awesome parts for the KA, just a forwarning though. If you do get their intake manifold with the plenum, check for small pinholes in the plenum itself. I did have a small one. Could have become a very annoying vacuum leak. Otherwise I love their parts!
