BIG 16g requirements

[micus]

hey i was wondering if i could run 22psi ( give or take a few ) on a big 16g, not a evo 3. with 550cc injectors, and a walbro 190lph fuel pump with a s-afc2. and still be in the turbo's efficiency range .or would that amount of boost require 650's and a walbro 255lph wtih an fpr?

If you're running on 93 octane yes you can run it with 550's and a 190. Tune it right and you should have no problem. If you run 91 octane than you'll need 650's with a 190.

yeah i only ever put 94 in it, i guess in canada premium is 94 ive never seen 93 as an option... but thats dope, i can save money on an fpr and i hear the 550's are easier to tune then the 650's with the s-afc

Damn you California and your Shi77y 91 octane.

Im running 680cc injectors on a small 16g with an SAFC2 but Im also getting tuned by my friend's Wideband. I personally wouldn't run more than 680cc on the SAFC2 because they say that 750cc are much harder to control. I have way more than enough fuel to run 25psi from my S16g but I would be way out of the efficiency range. Im aiming for 18psi this summer. I could go to 20psi efficiently with a frontmount but im still running a boost leaked sidemount.
