Hey guys, i got a 95 fd3s and im doin a single turbo upgrade with a GT35R. The mods i have right now is a Power FC, aftermarket exhaust, fuel regulator and some minor other mods. My question is what fuel mods will i have to do, if im goin to stay within 10-15lbs range of boost? Thansk alot.

10-15lbs? if you are not porting the engine and just slapping the turbos, I say get some 850s or higher injectors with stock 850s (4 x 850s).

fuel pump upgrade walbro something??

Sure, why not.. get some upgraded pump.. but in my opinion, I think if he's only going to run 10-15lbs, stock pump should be fine with stock ported motor. But what do I know... If he's going to run 15lbs all the time, be safe and get an upgraded pump, but I would go all out and get rails for top fed injectors and a regulator..

better safe than sorry.

True! Better safe than spending 2-3k on a new engine.

Thanks alot guys for the respones..ill be getting the walbro fuel pump but is it necessary for me to change the injectors if im goin to run 15lbs of boost??

You will max out the duty cycle on the stock injectors running 15psi. You should ugrade the secondary injectors to 1600cc. You can leave the primary stock 550cc in place. I would get a new rail, lines, and fittings to go with it. You said you already have the regulator.

I'd be real cautious of 15psi these days if you plan on running pump gas. Hopefully you have someone capable of helping you tune. I would get their advice.
