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 Drew

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.

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! |

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

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. |

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.

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

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?? Last edited by SLEEPERracer; 03-14-2007 at 03:42 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.

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.

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.
