My turbo setup
 

Am just about ready to put this together the setup is,
1998 1.8 nb 130000km
Sr20 t28 on a beigi cast Mani (internal wastegate), 2.75 straight through exhaust to back box, 255lph fuel pump, aem wideband, and u guys will be happy to here I am running an aem fic PIGGYBACK, it can control injectors well and pull some timing, it will do the job for now, I will only be running wastegate pressure for now which is 7psi I don't have injectors yet because I am still trying to figure what ones to use and what target boost/bhp I will settle at, all your inputs welcome pictures of the install to follow. Thanks.

Bigger injectors?
Inter cooler?

Sounds like fun.

FIC will work fine but has limitations. You can actually run them in a psuedo speed density configuration by emulating the MAF output. It allows you to elimimate the AFM.

Injectors = yes, or use a higher rail pressure. Those injectors will be running hot at 7psi fo sure. Supra green tops should do it, but they are old crappy tech. You could also boost the rail pressure, but I am not sure you can get there from here. Check out the injector calculator on witchhunter performance.

Thanks guys, I am not running the maf through the fic its alot easier setup, people have ran 700cc with the fic no problems, intercooler yet to come and I may just go with with the rx8 injector.
