Hi what is the brand of the fuel rail system for the turbo tbi. I have a 1993 I'm installing a turbo on and need help with raising fuel pressure.

[QUOTE=kbracing96;3213381]I did it on a 91 S-10 with a 2.8 TBI V-6. Same concept, just a smaller motor. I put 4.3 injectors in the 2.8 TB and used a rising rate fuel regulator to increase fuel pressure for boost. Worked good for 6 lbs of boost and pretty cheep. I had about 700 bucks in that whole turbo setup. Let me know if you have any more questions about the setup.[/QUOTE

Man it was a long time ago, lol. I think I did a write up one of the S10 forums but all i could find was this thread on it.

I am doing the same an have installed a gt3582 t3 turbo on the 2.8, I installed the 4.3 injectors with an external boost referenced fuel pressure regulator, haven’t been able to drive it yet cause snow on the roads, my only thing is I ran dual 2” exhaust into single 3” feeding the turbo, I’m wondering if I have gone to big of pipe and should try something smaller, it is running rich, I only ran it for a minute, but I guess that wouldn’t be bad once I start pumping the boost to it, wondering if I should buy some chip burning software or do you think it will run ok? I’m looking for around 6-8 psi of boost

did you re-tune your ecm? or did you just run the injectors with the fuel regulator?

I used a fish tank air valve to bleed air to FMU to raise or lower the fuel pressure when in boost. I ran the stock ecm tuning and let it use the closed loop stock O2 for normal driving and then raised the fuel pressure when in boost to make it run right. Get yourself a wideband gauge to tune it.
