im just planning out the future a bit here,

so my goal is to max out a gt35r (~650hp) on 91 octane pump gas.

anyone know what size of injectors i would need?

iv been told 850cc would be enough, but i dont believe for some reason....

650whp can be done on 850cc injectors without an issue.

650whp on 91 octane pump with a gt35r... that is pushing it and probably won't happen. 500 something you should be able to do on pump.

100% agree. You will be pushing it to get a LOT more than 500rwhp out of a GT35r on pump with no E85, meth, or race gas something. I've seen 550rwhp and a bit more IIRC, but your not going to make north of 600rwhp on pump. About injectors, 850cc's will be just fine. That's what I ran with my HX40 and it's only a **** hair bigger than a GT35r. I will say one thing though. Just get 1000cc's or bigger. People have no problems making that big of an injector idle on a 6 banger. It doesn't matter if you have 1000hp or 300hp. Idle is idle. People who tell you to aim for a certain hp goal when choosing injectors are morons and read too much SAU.com. Just get the biggest injectors that will idle well (and good 1000cc injectors will) and that lets you grow in the future i.e. more boost, bigger turbo, E85, etc. Your idle and fuel mileage will not suffer because your injector is too big for your max hp.

i will take that into great consideration.

550hp aint too shabby if you think about it. maybe ill just lower my hp goal a bit and when im finished my schooling will go bigger.

19 year old + rb26 kouki = dangerous lol.

thanks for the help guys

650 550 even 400 hp in any schassis is SILLY POWER. Unless your building a drag car or a death wish, you won't have the huevos to fully open up a 650hp 2800 lb 2wd car .
