Stock FUEL Pump Potential
Are all fuel pumps on S4s S5s the same? including Turbos and N/As? I have a 89 GTU, and was wondering fow how much HP does the stock fuel pump is good for?
I will be doing a 89+ Turbo II swap, with just an intake, 2.5 exaust, FCD, and stock intercooler. I am expecting 8-9psi. Will the stock injectors/fuel pump provide enough fuel, because I do now want to detonate my engine. hehe (I can NOT afford an AFC atm)

Well I have my stock GTU fuel pump right now to get power directly from the battery through a relay, and it bypasses the ECU which changes the voltage accordingly. (I think) Is there a problem when I put a walbro 255 fuel pump in, there will be too much fuel pressure?
