Ka Turbo?

[s14ButoDrifter]

Im thinking about buying the greddy turbo kit for my KA from a frend for $1500 . Will i need to change my internals as well? Or will the stock KA internals hold up? any suggestions on what to change or keep?

not really wise to run turbo on any stock application....as long as you dont run max psi for a long amount of time and you dont push your motor hard as shit it should be fine for a few thousand miles....if you have a lead foot it will spin a rod guranteed. other folks will give you specifics

quick answer - it will work, greddy sells it without tons of problems

bit more technical answer - KA ignition timing is far too advanced to properly run a boosted application. I would set base timing back about .75* per psi of boost planned as a bare minimum. I would also suggest getting an MSD boost timing controller, or something else that can scale back ignition timing in relation to boost.

I can go on and on about this, let me know if you've got any specific questions.

yeah read around but there should be no problems at all. wasnt it phat ka-t that made 502hp on a stock ka?

-it didn't last long at those power levels
-they were running an AEM, that means proper ignition timing maps, not trying to use the stock N/A timing maps for a boosted application
-Phat KA-T is a division of sound performance, which is a HUUUGE supra shop. They also happen to employ some of the best AEM tuners in the country ;)

hey im just pointing out the fact that it could be done! lol I know people running turbo ka's for years now with 0 problems. Thats on 6-7lbs of course the more you push it the less reliable but they beat on their cars and 6-7lbs is like 240hp to the wheels with the high compression.

the guys from KA-t.org are making huge numbers.... 2 of them are in the 530 range.

KA-T.org car makes 533hp 418lb/ft @ 26 psi

Well aware, remember, I'm a huge fan of the KA-T idea.

Are those guys doing it on stock internals? What are they using for engine management?

I think for a lower powered setup (i.e.; 6-7 psi, 200-250ish rwhp) using the piggy back on a stock motor idea is awesome. For high powered setups (for reliabilitys sake) I definitely like the built motor (but keep the 9:1 compression) and a standalone idea.

if you are.. just run 5-7psi.. i was gonna do what your gonna do.. had everything set already.. then BAM! S14 got jacked.. :mellow:

tuning is a huge part of making a turbo engine last and making good numbers. ignition timing, boost control and a turbo timer are important. Detonation will kill your engine (ignition timing), if boost spikes something will probably let go (boost control), your turbo needs time to cool down after you park the car (turbo timer).

you can make a junk yard kit for under 1000 bucks. will it last? probably not.

a good kit with quality components and proper tuning should last as long as the engine would normally last with out changing internals (as long as you don't run crazy boost levels).
