I have a h22a and was wondering what is the maximum boost that i can do with the stock fuel system with an fmu.....i am thinking it is between 4 and 5 psi tuned....someone clarify this for me.....

 

upgrade the fuel system.

larger fuel pump, injectors, fmu. , safc/ vafc, do a afc hack.

run around 6- 7 psi. tuned.

 

Not the question you should be asking. It would depend on the condition of the motor, the setup, your driving etc. "Yeah so I have this car right, how much boost can I run?"

 

I know what i can run on stock internals guys, that is not my question....with my current setup which is : t3 60 trim turbo, equal length manifold, fmu, tial 35 mm wastegate and a side mount volvo intercooler....it is a junkyard turbo kit pretty much, and i am not asking what else i should do, i just would like to know what is the maximum boost that i can safely run with this set up...my motor has 40k on it, and is a closed deck h22.....
