hello all. i am a noob! i have a 1995 s14 with a blown KA24 engine and a auto trannie. i just bought the car yesterday as is. it is stock with the exception of the failed s15 front end conversion lol, but hey the headlights and carbon hood are cool. i am looking for any advice, tips or critcism(where needed). i learned alot, and had multiple questions answered at the start of this thread. the original plan was to buy a whole sylvia front clip and do the swap, but the nazis in cali wont let that happen. so now, im going with the KA-T. im just worried about the smog situation. is it really feasable to remove all the stuff involved with the turbo every two years for smog? also, a good KA-T rebuild kit with everything to make it "bullet proof" so i dont blow the damn thing up. and what does a running stock KA with a 5 speed trannie worth? mine has an auto transmission.

If it's just a sniffer test you have to pass and not a visual you can pass the sniffer with the turbo on easily. You can also have the EGR tube connected to your down pipe so that all your smog stuff works like stock.

I have a quick question, I'm about to go ka-t and I've been told that i need to buy an OBD2 ecu if I want to tune my ecu because the stock OBD1 ka ecu canno be tuned... is that true?

That's the opposite of the truth. ROM tunes are available for OBD1 (less than 1996).

I assume you have a '97-'98 based on your name. So you need a '95 ECU to ROM tune. But will have the CEL light on and will fail inspection if you are in a State/County that has OBD2 inspections.

It's because we all fear the wrath of the worst moderator on the face of the planet.

Either that or it's because he knows what he's doing haha.

Just a quick question, would the stock compression ratio of 9.5:1 be safe to boost and make around 280-300whp??

With proper parts and tune, yes. I'm currently at 282hp.

Easily attainable with an off the shelf tune these days. Match your fuel management parts to a good tune, Enthalpy is currently the best from what I've read.

Figured I'd post this in here since this is with a stock KA. 280 whp is easily attainable with the right supporting mods, but I recommend at least 550cc's and a z32 MAFS before running more than 8 psi of boost.

Specs for people finding this thread by searching: 370cc injectors, stock MAFS, EFI Specialist Tune, GTi-R t28 turbo.

Didn't you pop your motor right after that dyno because you were running to much timing?

If you want that, just go LS1.
You know, I see this and cry lol. Turbo magazine, sister to import tuner magazine, has done a 750hp KA24DET build with the help of the founder of enjuku racing, whose first car happened to be a '95 240SX with a KA24DE (which is why enjuku was originally the go to place for anything Nissan). It requires a crap load of cash and time cuz you bore it from a 2.4 to a 2.6 and up size your head bolts from 10 mil to 11 mil, scrap the stock semi countered crank for a fully countered crank which involves modding the block by grinding to fit it. It's a nasty build and very risky and involves super intelligent chimps with doctorates in engineering :ohno: but it is possible to build a nasty a** 240LS-murderer.

Also, I learned through PMM on YouTube, who did some homework, that the 5 speed manual trans off the SR has a tighter gear ratio than the 5 speed manual trans from the KA and is completely interchangeable with a KA. All that is required is a swap of the bell housings, which bolt right up perfectly. So for all those inclined, it's a DIY mod so you can save some bucks.....just don't forget you clutch alignment too or s*** can go south fast.

I've driven some very high hp small cube motors, they all have one thing in common, huge amounts of turbo lag. Usable power from 5000 and up isn't fun for anything other than going in a straight line.

By going with an LSx you can have a motor that makes over 300ft lbs of torque at throttle tip in, by just dropping it in. With a cam, intake and rom tune you can make over 500 ft lbs. We're talking about a car that pushes you into your seat from the second you touch the go peddle to the point where you lift. Traction will be a thing of the past.

I love the KA, but it will never beat the LS series where power is concerned.

Not a lot of SR transmissions lying around though. The ones you find are usually beat pretty badly.
