Hi Guys,
I have a mate with a r33 gtst like mine. He has exhaust, 12psi on stock turbo, fmic, & pod, and has recently upgraded to the Bosch internal 044 i think it is, and reckons towards higher revs the car goes harder.
I have same mods as him, but instead i have the r34 GTT cooler. I am planning to upgrade to the bosch fuel pump, as the stock fuel pump is more then 10 yrs old. But do you guys reckon it will make a difference in performance, especially towards higher revs???
Anyone done this before??
Feedback would be appreciated
Cheers
