I'm going to put back in my Jwt cams, and run again.

I'm also looking at running advanced ignition timing up to 23 degrees, coolant bypass, Iridum plugs to keep the temps down from the increased timing. anything else you guys can recommend?

Oh yeah, its Auto.

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.
The ECU and Cams (not on this motor yet) Are JWT for the record.

Iceman00 · 06-08-2007, 07:29 PM

For the Record, why didn't the fag who Neg Repped Me leave his Name. Idiot. I chose to mod my car for me, and not for you.

what kind of dyno was that on?

because on a dyno pack a 92 ka24de w/ just an injen intake w/ extension, hotshot headers, hi-flow cat... nvidia catback (no resonator) jwt ecu managed to make 146 whp...

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).

*swayray* · 06-09-2007, 01:28 AM

oh yeah.. i mean rear hub hp... i think its 15 hp more since there's no drag from the wheels...

wow... auto + stock cat/exhaust... that's pretty good!

Iceman00 · 06-10-2007, 06:18 PM

I'm hoping for 155whp After cams and exhaust

infinitexsound · 07-15-2007, 01:59 AM

there needs to be more updating on this thread,

as of right now im rebuilding a sohc with a hybridka cam spec of
Intake 270 duration, .443" Lift
Exhaust 272 duration, .448" Lift
with springs and stainless steel stock sized valves
with head work.

if anyone has swapped out pistons please post up some info, id like to know what kind of numbers you got with what ever pistons u used... keep in mind that im using nissan oem pistons. so no aftermarket performance ones please

ill post results when im done.

*SexPanda* · 07-15-2007, 02:26 AM

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, 08:35 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...

2_fast_240 · 08-03-2007, 03:11 AM

And its acually on all s13s, not just sohc. Just to clarify.

Whoever neg reped me on this is a douche bag. Saying "you wasted your post". WTF. This is suppose to be information about the KA from what I understand. The two posts above made it sound like the only KA's with the butterflys were SOHC. Just trying to help people out. But, who cares right. This can be deleted now for all I care, just wanted to put that out there.

Iceman00 · 09-01-2007, 08:04 PM

Best way to tell if your cat Flows like shit? I'm putting my cams back in, in a few weeks, and then I'm going to head back to the dyno, and un-bolt the exhuast, and run Open header. (if they will allow it) Hopefully, I put down so respectable numbers.

*DALAZ_68* · 10-11-2007, 03:02 PM

ok heres my situation...i dont wanna deal with turbo or super charger (ATM)

and im ripping out my s14 KA from my 90 chassis (runs and sounds like shit) and dropping in another (much better less milage ) s14 KA in there...

wut to do with the S14KA i ripped out...im really considering building it for N/A powah!!

once its out im cleaning up the rear of the mani (i.e. emissions B.S.) and since its already running cruddy (Compressions low... cant figure out why) i wanna rebuild it for some fun

ima have aroung 900-1k worth of funds for this
i wanna get bang for buck basically

but im very limited in my knowledge of cars in general (no matter how many times i read books about them) that i need some serious help here

car already has a single piece drive shaft and KAAZ 2 way dropped in...which i did notice a nice change in response and Exedy stage 1 clutch and 2.5'' pipping wiht high flow cat,

so im wondering once i rip this fucken thing apart...what the best route to take to gain some ponies on this thing...ive been debating wether to do the s13 cams and some new lifters and springs on its ( probly some aftermarket ones if the price is worth the gain) rebuild...

any suggestions id love to hear...

i wouldnt mind doing the iTb's set up....but i live in the heart of L.A. ... nuff said on that

bntmoore · 10-13-2007, 03:25 PM

if i was you i would just save up for a full sr20det swap, cuz after you rebuild your old ka your not gonna have too much $$ left to do any worth while upgrades. just pic up a sr and slowly build that until your ready to swap again.

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

sav180 · 11-13-2007, 07:50 AM

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

try n spend a extra 400 n get some 11.0.1 high comp pistons from JE should give you some good power gains on top of that.im runnin those on my set up now.im just tryin to find a good intake manifold.thinking about getting a

alot of guy from the ka-t.org are runnin those.so hopefully one of us N/A ka hopefulls will put out some good #'s and get more people to do the N/A setup on the ka and kill off the haters

..

sav180 · 11-13-2007, 08:04 AM

you should check out pdm they got a 240sx thats pushing out almost 200hp on stock internals and dyno chart to prove it...

"ECU tune with cold air intake, header, exhaust and running 104 octane we found 177 RWHP and 182 ft/lbs Torque.

All these numbers were found on the engine with stock internals and 250 000kms on the engine already.

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?

*NemeGuero* · 01-28-2008, 01:14 PM

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.

How would the Wiseco 90.5mm(Disp. = 2470) bore 10.5:1 C/R Pistons hold up to the JE 89.5mm(Disp. 2415) 11.0:1 C/R Pistons?

sav180 · 01-29-2008, 05:41 PM

hmm i would say it depends on other parts u have and the tuning

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...

twistedlanes · 02-14-2008, 08:18 AM

For you guys running itb setups...do you have filters on the or run them open like that?

Nismo240R · 02-19-2008, 11:25 PM
