My mods so far are non sequential turbos, dp, mp, cb, pfc, intake, manual boost controler, and I have the greddy 3 row on the way in the mail. My plan was to next upgrade my fuel system, and I would like to see what you guys recomend. My future plans(september hopefully) are for a t-88 single.

 

There's a ton of opinions on fuel systems. Search the single turbo area & choose which one is right for you.

If you use 1600cc injectors you will need resistors for impedance matching & a datalogit as the commander only alows for sized up to 1400 or something silly like that.

 

Put your 850cc secondary stock injectors as primaries (requires some modifications - nothing major) and then put fat ones in the secondary position... 1200-1600cc units.

You can buy a second stock pump and run twin pumps, which requires modification of course to fit them both and set up the lines and connectors, but you will end up with a lot of fuel flow. I know 2 x TII pumps = 320 lph.
Another option, probably the most comman is to swap in the Walbro 255 lph pump or the RP (www.rx7.com) 255lph pump.
