OK, all. Here is the setup I'm going to be running.

16G Mitsubishi turbo, T3 style flange.
2.5" FMIC & piping
EBay manifold
custom 2.5" exhaust.
Accel 440cc injectors
Accel adjustable FPR
AEM UEGO wideband O2 sensor
anywhere from 7-14PSI.

My questions are, what ratio FMU should I run??? I plan on going with a set of Accell 440CC injectors (Well 426cc-44lb/hr, whatever). I know I'm going to have to lower base fuel pressure to 25-30 PSI for idleing, and don't want to worry about injector clipping at high boost/ fuel psi levels.

Also, what would an ideal "safe" air/fuel ratio be for decent power??? I've seen anywhere from 11.0-12.5 as being suggested.

Also, the fuel pump. Walbro 255 of course. Inline or in-tank, what is your suggestion???

And finally, what is the recommended oil pressure to be running to the turbo????

Thanks for any and all info.
