As of a week ago I knew nothing of turbos, other then the basic principle of their operation. Now after a week of research I have a much better understanding, but have a question I haven't been able to find an answer to yet.

I read this:

How much boost can my car run safely?
GSR-Stock Internals 6-8PSI.

Note: On a stock map sensor, the amount of boost you can run is limited due to the fact that it doesn't know what to do with it, and throws a CEL code.

OBD1-2 .75 kg/cm2 = 10.66 PSI

Now I have a 2000 GS-R so my question is, if I only want to run 8 psi of boost can I do this with my stock ECU and fuel system?

I would rather save the money of getting a FMU, injectors, and fuel pump and instead spend that money on a good boost controller (ie: A'pexi AVC-R), and good wastegate to make sure I don't go over 8 psi. After reading that article it seemed like my ECU and fuel system is designed to have a turbo just as long as I don't go over 8psi.

What do you guys say?
