hi, the time has come to get myself a new turbo for the rebuild and after some pointers on specs etc.

current engine is a 1600 cvh low comp with big valve head 285t2 cam and grs twin pass fmi. looking at running 20 psi so would a stage 2 be too restrictive or would i be better off just dealing with a laggier stage 3. then there`s comp wheel sizes?? 55 or 60


lastly the actuator, would a -34 be best choice as looking at 15 stg1 then up to 2o stg 2.

cheers.
