Which turbo would be best for shooting at 7-8psi on a GSR? Considering spool up time as well.

 

What kit or other pieces are you using for the turbo setup? What are your power goals? Too broad of a question.

 

DRAG cast iron or tubular exhaust manifold
Turbonetics-Garrett T3/T04B or E-trim hybrid turbo
Spearco intercooler DRAG aluminum end tanks
Turbonetics Deltagate wastegate (5-7 PSI)
Greddy Type-S blowoff valve
2.25-inch chromed, mandrel-bent intercooler piping
2.50-inch mandrel-bent down pipe
Vortec fuel management unit
Purosil hoses and stainless steel clamps
Airtex high pressure fuel pump
Stainless steel braided oil feed line
Installation hardware package

Accessories


HKS boost gauge
HKS Type 0 turbo timer
HKS Variable Boost Controller (VBC)
Missing Link check valve

Im guessing that at 7 psi I would have about 250 HP...that is really the goal.

 

Totally depends on your goals for the car/engine.

I would most likely reccomend a SC50 from precision.
