ok, i did alot more searching and still nothing. i know at least one member here has this header. can anyone tell me where to buy one?

Ichito240 · 05-21-2009, 09:46 AM

Another Headers question that might have been answered already. Are the DC Headers CARB legal? Have an 98 KA and want some added power but still want to pass smog in California.

thanks

TravisSW · 05-21-2009, 05:14 PM

DC headers are CARB PENDING
Still illegal.

my bad guys ben busy as h@#$ ..got the block build n threw main n rod bearings,the guy that did it mixed up to rod caps n it chewed the whole block up,crank n main girdle..horrible..but lucky me i had a spare block n crank n my machinist fixed my rods so im jus waitin on the block to get back to me next week thurs fri..

project-D180 · 07-23-2009, 10:55 PM

i went over sized je pistons i had and it should be straight..i will be putting my own block together this time..

any other n/a heads in jerzy is welcome to swing on by help or chill

project-D180 · 08-20-2009, 11:14 AM

she's aliivveee..lol ..just gotta break her in and get a dyno run..will be posting pics soon

dRift_g0ddess · 09-18-2009, 11:53 PM

so ive read all 7 pages lol.. and i heard not much about fuel pump/injectors?? just leave stock? or would a bigger fuelpump/injectors help alot?

im looking at putting the bc stage2's and valve train, i/h/e, port and polish head, jwt ecu, ported tb and intake.. anything im forgetting?

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.

project-D180 · 09-19-2009, 01:06 PM

well im runnin a walboro fuel pump with a tuned ecu with stock injectors for now

project-D180 · 09-19-2009, 01:07 PM

im lookin into gettin v2 cams myself but thats gonna have 2 wait till next year when i come home from school

project-D180 · 09-19-2009, 01:13 PM

im curios on 0bd1 can you use the z maf on the stock/tuned ecu

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?

*let5l1de* · 09-21-2009, 01:27 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.

*WagDatto* · 10-02-2009, 09:02 PM

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!

*let5l1de* · 10-04-2009, 03:52 AM

Don't we all wish the foldout page of the FSM was available within these pdf's?

First of all, please confirm you are working with the late 95 model or true OBDII version.

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".

I know this is confusing but I hope it helped.

^^ 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...

project-D180 · 10-07-2009, 01:35 AM

hell yea its a blast drivin it ..im still breakin it in but it has alot of pull even though im not revin pass 5 grand..runnin 11.0.1 pistons eagle rods,balanced crank n polished,ported head stock cams though for now,tuned ecu from efi specialist,intake,headers,exhaust,aluminum driveshaft,2way tomie diff,stage 2 clutch,xcessive intake mani,stock tb,3 angle vavle job,set my vavle lash tighter to cut out most of the tappin stock inj fn maf for now.

J-F(rx-team) · 10-08-2009, 10:11 PM

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, 02:19 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

Jus get electric cut outs.. open dem wen u gonna race watever be loud.. comes are in site jus close dem up
