Selecting a Turbo
Commonly used ones :- T3/T04E 0.60
- T3/T04E 0.57
- Modified T04E 60trim in a .60 cover with a stage III wheel in a .63a/r. (Kinetics?)
- T04e-57 (EIP?)
- GT30r
Fueling
Boils down to two general options : increasing the fuel pressure or using larger injectors. If you were to get into monster-turbo builds you would probably need a combination of fuel pressure regulator, inline fuel pump, and injectors.On the stage I and stage II kits Kinetics/C2 goes for larger injectors on stock FPR and EIP goes for stock injectors and higher fuel pressure.
