I am currently running an EVO III B16g and the stock 450s, uip, GM MAF-T, 3" exhaust, Walbro 255, etc. Well as you may have guessed, I have maxed out the 450s and am now looking for what to upgrade to. The options I'm looking at are 550s and 680s from either FIC or PTE. I'd like to stick with the same turbo for a while, even after a built motor goes in. Now the question is, will I max out the 550s with this turbo (running ~25psi)? I have a friend here at school that has a B16g, FMIC, etc and 550s and is convinced he has maxed them out at ~22psi.
Also, if I were to go with the 6xx injectors, would I need a burned chip to compensate for the idle or would I be able to iron things out with the MAF-T? -------------------- Eric

QUOTE (lawngsx @ Dec 16 2004, 06:20 PM) Sounds good. The next step is, with 680s am I going to need a custom chip to get the idle right or will the apfr and the MAFT-T do the trick? If you already have a larger fuel pump, a MAFT and an AFPR/fuel pressure guage will do the trick for larger injectors. |
