I am wondering what type of fuel systems (piggy back or complete) are available for the MR2 turbo 91. I am looking to run mid to low 12's. Is that possible with the S-AFC and larger injectors? I am planning on running a td06. In your opinions what is the ideal/cheapest fuel set up. I know you can run 12's on stock fuel system but Id prefer go aftermarket with some of the components.

Technically the SAFC is part of engine management, not the fuel system.

I am in the 11s (11.7-11.9 range) and I am currently using:
550 injectors and Aeromotive Adjustable Fuel Pressure Regulator (www.trueleo.com/fpr.htm)
I am tuning with SAFC & VPC.

With proper intercooling and fuel choices, you can get a TD06 into the 12s without any fuel mods ... granted you will not get deep into the 12s.
