i current have gsc 280's in the car, these arent the s3's though. i was wondering if i would have any benefit running the s2's? right now the car is torquey as hell, which i love and it pulls pretty damn hard when not in boost. just wondering if there was something i could use to produce more power, maybe spool the turbo faster.

here is my build so far

why not go with the GSC R2's i think english racing had them developed for big bore motors.
