Ok i purchased a 96 M3 and i am almost done turbo charging it but have run into some problems. My main problem is i have a B.E.G.i raising rate fuel pressure regulator with 36lb injectors and it is just not running well. When i put new injectors in i had to lower the fuel pressure or else car ran to rich at low rpms and had a tough time idling, I am thinking the injectors i got were to big but not sure. I am only running about 5psi of boost and when i try to floor the car it hesitates at about 3-4rpms and only gets past that if i ease the peddle. i am running at about 23psi of fuel pressure would getting smaller injectors fix my problem and raising the pressure to about 45psi. when i had it up that high with those injectors i the car would run with no hesitation but would not idle almost at all. My second issue is my turbo has no room for a air filter because of the engine mount and i don't know what to do. Please help anyone that knows this **** or has had these issues.
