T3 TURBOCHARGER45 trim (21lb/min). 42 A/R COMPRESSOR . 48 A/R TURBINE

and a

T4 TURBO . 60 - T COMPRESSOR WHEEL GARRETT INTERNALS T04 " P " 1.05 A/R TURBINE HOUSING COMPRESSOR HOUSING A/R .60 TO4E INDUCER 2.324" / MAJOR 3.00"

If anyone could help me out with my decision i would greatly appreciate it. im trying to build my KA-T bulit proof with 350-400HP , i alwayse think bigger is better but i dont want to screw it up. thanks everyone

t3 soulds like the one i just picked up and its only good to about 250max i beleave.....maybe wrong but i would probably got with the t4

go with the T4 definitely over that T3. that T4 will have lag to it due to the size of the back housing but that T3 will never get to those HP figures. BTW, that T3 is too small for the KA IMO.

the t3 will make little power, and the t4 is too big for any fun on the street. Go for a .63 a/r T3 turbine housing (hot side) with a T04E wheel, the 50trim is the most common for street apps, if you are looking for 350-400 hp (300-350whp) then it will be perfect, if you want more, I would personally rocommend a 60-1 compressor on the same turbine housing.

You won't see boost until 6000 with the TO4. I have a .81 here and I didn't hit boost till over 5000 on my Skyline.

The T3 is smaller then I'd use but it will spool very quickly and be good for street and track.

I thank everyone for the info..... as soon as i got the last few post i called to see if they had sold the t3 and it is gone , but he has a few more turbos left so im waiting for a call with what is left. i will post all info that i get ......5 grand is a ways up there for the t04 to spool up and im sure as soon as you get good boost your pegging out at 7 grand ......

ok this is the spec on the other he has and from everyones opinion this should be the ticket i would love more info if you see something in the spec's that may not be good for my project " please excuse my spelling"
