I am interested to know what kinda power you guys are making with T3 turbos. I'm considering a Z31 T3 (60trim, 0.60 AR comp and stg 1 wheel, 0.63 AR exhaust). I personally wouldnt go any smaller with the turbo since I heard so much about top end flow issues. I like the idea of quick spool of a T3 compared to T3/T4.

I know these kinds of questions are posted alot, but I did spend some time this morning searching thru threads for info. Here's some info I found (all these are on a KA24DE)...

http://www.nissaninfiniticlub....54263erich mentions his dyno numbers here. Hes using a ball bearing T3 with the same specs as Z31 T3 (I assume hes using a bigger exh wheel, stg 3?)10psi - 224whp14psi - 242whp

http://www.nissaninfiniticlub....10835In this thread, zb240 says he made 285whp at 16psi on a T3 (dont know the specs). No dyno sheet to back it up. Would you guys doubt this claim?

http://www.nissaninfiniticlub....ber=2in the KA-T poll sticky, kaje36 says he made 213whp / 226lb-ft at 6psi with a T3 (45 trim comp wheel, I believe)

I understand that a T3/T4 setup can carry me as far as I'm willing to push the stock KA (15psi, nearly 350whp) . But how far can the Z31 T3 go with excellent supporting mods (eManage, 50lbs, 91 cams, 3" turbo back, big FMIC, even alky injection)?? Is 300whp unrealistic from this turbo (at 15-16psi, the point where it makes more heat than power and I start to worry about the KA holding together)??

I am using a stage 1 turbine wheel, at least I think I am as I didn't ask for anything special with the turbine.

I think most of them come with a stage 3 wheel (at least all the t3/t4 Ive seen). The Z31 T3 is the only turbo I heard of with a stage 1 wheel.

Can you tell me your setup for these 3 dyno runs??http://www3.telus.net/kreen/im...0.jpgI saw your latest one at 14 psi. Is this with the setup you have listed on your site?

BTW, I really like your headlight mod.
