Blue Evo 8

I was wondering what size injectors would be approproate for a GT35R EVO at 30+ psi of boost?

Are my stock injectors sufficient for my stock 05 turbo running alky and 28 PSI??

I would say 1000CC injectors.

The 35r will max at about 650whp. Most people who own them don't make over 600whp. Stick with like 880s because those will max at low/mid 600s.

i would say at least 1000cc +fuel rail, FPR for the 35r, but your stock injectors should be ok @ 28psi. your stock ignition system however will not keep up over 27psi though. get 2 step colder spark plugs & an ignition amp. if you already have a walbro u should be good 2 go.

If you plan on using most of that 1000cc injectors, you're going to need a bigger turbo and with that, you're going to need an entire fuel system (dual pumps/one bigger-than-255lph pump, -10/-8 AN lines, AFPR, etc etc... ). . Why do people get bigger injectors than needed unless you plan on going bigger later? If you're going to do that, you might as well just get the bigger turbo now then? I guess I must be missing something and don't get it.

I'd say get 1000CC just incase you need it later, doesn't hurt.

My 1000's are at about 75% on a conservative tune at 30psi

FIC950cc injectors, thats what I run on my Eclipse. The IDC at 27psi + Meth on 93 octane never passed 65% with the stock fuel rail.

There is no need for 1000cc injectors for a GT35R. 880cc is plenty.

About the only way one finds a need for 1000cc injectors in a GT35R application is if he is running an AEM EMS, and only because the EMS has the WRONG injector drivers for the EVO.

The EMS is configured for low-performance high-impedance injectors. The EVO comes equipped with peak and hold, LOW impedance injectors. Few people are even aware of this, so they just spit out injector sizes without rhyme or reason.

The EMS cannot control low impedance injectors correctly, so oversizing the wrong impedance injectors is at best a band-aid fix. Of course, one can change that by investing another $300 in AEM's low impedance injector driver upgrade. Just FYI.

And yes, stock injectors are fine for a stock turbo 05 running 28psi in the midrange and meth injection.

^agreed..

right now im running 880's on 33 psi on a 35r but im gunna have to check what % im running at, anyone have a clue what i might be running.

It all depends if you are using a Standalone or a Flash. I hear you can get away with 720's with a flash and a GT35R.
