I have a T3/T04E and I don't know the specs on it. The only number is 50 on the compressor housing but it says A/R first(A/R 50). BTW its gong on my H22 EG6 I wanted to run 1 bar on it (don't worry its fully built darton sleeves and forged internals, entire rotating assembly has been balnced) will it be big enough?

Oh BTW redline is 8000rpm was originally a NA motor Untill I wrecked my Prelude but compression will be lowered to 10:1 is that too high. I'm a noob at this turbo stuff more into building high reving NA motors. But its a lot easier to get power from turbos(welcome to the darkside)

 

10:1 is pretty high for 1 bar. you might want to consider running less boost. and prepare to spend alot in tuning.

 

Tuning is free my friend is using crome to tune it and his shops dyno. Should I run 9.5:1 I want off boost driveablity

 

honestly i would run at the most 9.5:1 , and w/ an H22 off boast is still gonna rip w/out high compression.
