I have a t3/t4 from a CRX revhard kit. All I know is that it is a t3/t4 and inside the little opening on the compressor side(not where the blades arre, the other one), it says .50 trim. I don't even know what size the exhaust side is or the turbo side. Is this good enough to generate at least 400 wheel horsepower without it starting to gasp up top?

 

I don't know if u can be sure that is a .50, but we had a .50 on our racecar and it made 496whp at ~28psi on a 1.6L
