Just a simple question, tried searching and found only info on evo turbo upgrades.

Does anyone know the exact difference between RRM stage 1 and stage 2 turbo kits? If I come into a used stage 1 for a good price I'm gonna want to upgrade, and ideas on the cost of this?

 

call RRM but u need an I/C from stage1 or buy one for stage2

stage 2 has bigger fuel injectors to supply ample amount of fuel to your engine for the increased amount of power you will be getting due to the updated ecu you get thats tuned for 9 psi. pretty much you get injectors and the little ecu. OMG i cant remeber its name is it fmu? bah!
