75 911 CIS need to up the boost on turbo
I have a 75 911 that I just put a t3-t4 turbo on. I can only run the boost at a little over 4lbs without fuel starvation. any suggestions on larger injectors or fuel pump. I do not know much about the CIS. By the way I have a '79 3.0 in the car right now.

not only fuel will be a problem, but you can only put so much boost into a car that was originally a normally aspirated engine. I have an 83sc cab and everyone said not to turbo charge the factory motor i would blow it up so i have a turbo motor dropped in.

the car originally had a different motor. The 3.0 has been rebuilt by the previous owner. I replaced the turbo because they had way to large of turbo on the car(it would not spool).
