I understand that I can swap a trubo engine into my s4 n/a... but can I just buy a complete aftermarket turbo kit for it instead?

 

you can, however its just better if you pick up a jdm turbo II motor.

 

There is no such thing as a complete aftermarket Turbo kit.

There are Turbo upgrade kits for factory Turbos.

There are people that every couple of years say they have or will have a turbo kit for a non turbo. But they never seem to come available.

And all this is covered in the FAQ for FC sticky thread found at the top of this, the 2nd gen RX-7 technical section.

 

Alright, thanks a lot... I need to start searching on the F.A.Q. more often. Thanks a lot Mark.
