? on R85 turbo

[silverfd]

Car is a 93 FD. I already have the R85 turbo and installing it on a rebuilt street port motor. What in-tank fuel pump for the R85 turbo, that can support up to 600 hp. I don't want to run a sumped tank. I also want to try to stay away from twin fuel pumps, in case one fails, i could ruin the motor. Mods listed below. How much boost can the R85 turbo take? I think i saw someone running 27lbs. Can it push anymore before running out of breath? I have a pfc map for the r85 from a tune from someone else. Would i be able to download this for the start up and break in period to get it to a dyno. It is tuned for my injectors, and 3 bar map sensor which i have.

I wouldnt rely on anyone else's map for anything other than to get you up and running. Definately would recomend getting it tuned for your specific car

Does the R85 have the extended tip technology ?
