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!!

Peace

Im running an 3" SR downpipe on my S13 KA... just have to use an S14 exhaust mani.

i will have to second that!!!! u can use a s14 exhaust mani on a s13 and will bolt to a sr downpipe.:wackit: ftw

OK so that is confirmed as possable... But It dosn't work on the S14, seems odd!?!

so question about stand alones. do you need one for itbs or could you get away with a piggy back? my guess would be no cuz i dont think you can get rid of the maf with just a piggy back but just askin to make sure. might make things eaiser down the road.

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

meh alright, i figured id ask, megasquirt here i come.

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!

I'm pretty Sure the title Reads N/A KA. Lets keep it on topic

ms!3 02-12-2007 02:30 PM

how is talking about ms going off topic?

Iceman00 02-12-2007 04:20 PM

48, 49, 52, and post 59.

ms!3 02-12-2007 06:01 PM

merr.... i can see what your talking about with the supercharger thing. didnt see that , haha. but back on topic anybody have any info on the sohc piston swap. i heard about it alot but never seen anybody actually do it. id like to do it in the future, have grooves made for em so the valves dont hit with bigger cams. i dunno mabey have em polished to help reduce carbon buildup. werd is that they bump compression from 9.5:1 to 11:1 and with high comp rings that just might up the comp up a little. seems like a pretty cool thing to do to dohc's, just never seen it done. but then again you barely see "built" n/a ka's. lol

Iceman00 02-12-2007 10:52 PM

Cam it. And don't do the bullshit 248/232 swap with factory cams. JWT or go home.

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

Iceman00 02-13-2007 03:37 PM

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.

ms!3 02-13-2007 05:57 PM

well ive got an s13 and suposedly the exhaust is 248 duration and the intake is 240, swaped another s13 exhaust cam inplace of the intake cam, retarded the timing 3 teeth. 248/248

There is now a thread on this, check it out.

shinrekka 02-27-2007 05:48 PM

Anyone running the nismo R4 cam on their SOHC?

SLEEPERracer 03-14-2007 02:49 AM

im thinking about picking up this 97 dohc motor just cause it has hella less miles then mine does now and build an N/A setup. my 93 motor is pretty much the same so the trans would be able to fit and wiring harness and such rite? the 97 motor isnt gonna come with a wiring harness thats why im asking. i can run the same ecu and everything??

would it even make sense to upgrade fuel pumps and such and to tune it for power??

for now i was just thinking about running i/h/e and jwt cams? think this would be a streetable setup??

sav180 03-14-2007 11:00 AM

im gettin my block done now .runnnin je 11.0.1 pistons,eagle rods..jus got to get head work,itb's and a standalone.gotta prove the haters wrong

Ameer 03-19-2007 09:33 PM

Question is, will an N/A KA 240sx ever hit a 10 second quarter mile?

Ameer 03-19-2007 09:36 PM

I believe that it might 11.9 if you try your hardest. But I highly doubt 10.9 or better.

SpdElemts 04-27-2007 12:56 AM

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.

Iceman00 05-18-2007 10:33 PM

Just Had My KA Dynoed
Intake
Header
Ecu
Pulley
Stock cams and Exhaust
138hp/155q

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.

sideview_180sx 05-28-2007 11:45 PM

since you have more drivetrain loss due to auto I would be wondering how much more you would put down with 3-inch exhaust, and crower drop-ins. I'm looking if anyone else offers a sohc cam beside the R4 and R5 offered through nissan motorsports and the ones thru PDM.

shinrekka 05-29-2007 10:07 PM

wow all these people on this board and no one is running an R4 cam.
