i have a t3/t4 .50a/r compressor .63 a/r turbine and a 57trim just wondering if this turbo can produce good power on a gsr boosting 1 bar or should i get a bigger one.

 

its not psi that matters.... what are you looking to make hp wise?

 

No that Turbo is perfect thats what Im using.57 trim out flows even the 60 trim.I called Turbonetics and told them I wanted to make 350hp on the street and then boost up to 450hp at the track.They recommended the T3/T4 57-0.63 stage 3 supports up to 550hp.
