horsepower, parts, performance etc

[CJ7jeepLTD]

hey i figured id start a tuning type of thread, i have a 89 240sx with a 91 ka24de in it, i have obx header, catco cat, magnaflow exhaust, mugen (ha thats right) intake and thats about it for performance, i heard that a 300zx fuel filter would be good but i dont kno where to get one? napa? and if any year 300zx fiilter would work? i also was wondering if anyone has used a venom 400 computer? does it work, does it give you 25% more horsepower etc.. i was planning on also installing some unorthedox underdrive pullies. does anyone know how much horsepower my car would have with the before mentioned exhaust and intake mods, with no ac (if it matters). also if you guys know any other sweet mods i could do without getting into the block yet. i was thinking a limited slip rear end and i heard it shaves a second off your quarter mile time plus im tired of doing one wheel wonders ha. but im not sure how to get one? do they make them or do i have to rip them off a different car? other just just any performance ideas you guys know or any help at all would be greatly appreciated, p.s. sorry for the ****load of questions

I don't know anyone that had a venom computer, but everything I've heard is that it gives you more power when your not on the gas, but full throttle it doesnt effect performance much. I'd estimate your somewhere around 145 whp-a guess. Cams are a good thing for power, and limited slips differentials wont take a second off your time, but it would help. You can get aftermarket LSD's such as Kazz, Nismo, etc... or a factory one from a Hicas model, S14SE, Infiniti J30, 300zx.

thanks man i might check out that computer, did u say 145 for horsepower? i thought a stock ka24de put out near 160? maybe im wrong, thanks for the help with the lsd's. but i have a silly question. how do i kno if i already have a lsd? is that possible? someone repainted my car and so i wouldnt kno if its a se or whatnot. i heard you can get a intake manifold how much does that help, anyway thanks for the post

[corn322]

stock de's put out 155 hp at the crank. wheel horsepower is signifcantly less, due to losses in the drivetrain.

look on your differential for an orange sticker that says "VLSD."

Someone is in the proccess of designing/making intake manifolds for the KA, but we're yet to see how much they will really help. word is it will help top-end breathing a lot.

perfect compression DE's produce 135 at the wheels. Then again, at this point in time, very few people have perfect compression DE's.

skip the n/a mods. They are a waste of time and money. Go straight to forced induction. Youll be happier and have a faster car in the end

You know, that's what everyone says. Yet nobody I've seen has ever seriously attempted a naturally aspirated KA. Seems like all anyone considers naturally aspirated is a header.

ha ya and by n/a im assuming thats none turbo? forgive me ive never heard it put that way before. ive always thought about turbo but i dont have the money. how much would a exhaust manifold, downpipe, and turbo set me back, plus the remap boost bov and everything else? alot prolly, thanks for the help with the lsd ill take a look at that, does anyone know what year that 300zx fuel filter should be from? anyway, thanks for the post, always lookin for more power but pockets arnt deep enough, ya know how that goes. ive got a race comin up with a buddy of mine 2.2 honda prelude? 160 hp stock with cat exahust and intake, so well see. so i hear racing a honda is like running in the special olympics, even if you win your still retarted muaha (no offense to anyone out there, just a joke)

im gonna have to agree if you are looking for over 200 at the wheels. try to stay away from stuff that cant carry over. you already have the header and intake though so theres probably not much else you would be looking at.

so far ive dropped about 1.5k into my ka-t project, and still have a few things to buy. lsd's are a whole bunch of cash unless you just want to get a vlsd from another nissan.

ha ya and by n/a im assuming thats none turbo?

NA= naturaly aspirated as is air flows into the engin because of the vacume created when the piston lowers in the cambervsforced induction such as turbo and super chargers as well as I think no2, where more pressure is forced into the cylinder then their would normaly be under normal vacuume

[CJ7jeepLTD]

so what im hearing is to go turbo for the ka's eh? thats cool, i dont know that much about turbo systems though, bare with me, you would need a exhaust manifold, downpipe, turbo, intake/intercooler, and what else? where could i get these parts any reccomends? prices? other then that im gonna put a new crank ulley and e fan on her and then save up.... if i can, ha

[Red coupe]

there is a whole nother section of the form dedicated to it, check out the KA-T section and check out the blinking search button alot if not all of this has been discuse.

alright so if we were to list the upgrades done to the ka engine and 240sx car without going the turbo or internal route what would they be. obvious, underdrive puller, e fan, intake, header, full exahust. maybe a venom400 computer and what else? any other tricks to releasing power in the ka? would a 300zx fuel filter and injectors help or not cuz its not turbo? the bottom line is im looking for more power without taking the engine back apart and without getting a turbo setup (lack of funds) other then that any ideas or tricks etc would be helpful thanks
