Im in the process of collecting parts to boost my 7afe, and had a question about the fuel system. I have read many different things about it, and was wondering if someone could provide me with the correct parts i will need to upgrade my fuel system. I plan on using the supra 7mge green top high impedance injectors and an st185 celica alltrac fuel pump. I have heard that using a 2bar map sensor from an mr2 turbo is the only other thing you need to run the larger injectors and i would like to know is if that is true?
Or do i need some type of piggy back fuel controller? I have an safc2 in my garage, but if all i need to do is run a 2bar map sensor for the ecu to adjust fuel delivery, that would make things a lot easier. And will i need an adjustable fuel pressure regulator or rising rate fuel pressure regulator, or will the oem one suffice? Your help is greatly appreciated! |

2 bar map sensoe and 2x the stock size injectors = an acceptable tune.
iirc some year rx7 injectors are a good match good idea to have a piggy back though. the search feature will be ur friend. -------------------- QUOTE "And, as always, your friendship, help, and dedication to the advancement of Texas Celica dominance is GREATLY appreciated.
