Hi ... i've perused these forums for a while from over the pond and this is the first time i have not found the info i'm looking for.

Basically my Evo Viii Short block is getting uprated to a forged 2.2 stroker. I have GSC S1 cams in the Standard head and an FP Green installed. I want to max the Green out on the 2.2 but cannot find any concrete evidence of compressor maps for a FP Green.

I need to know how many Psi a green will pull to say a 8krpm redline on a 2.2

All i can find on the Fp website is this

"The 69mm 5blade CNC machined compressor wheel has a flow rating of 47lb/min and pressure ratio capability beyond 3.7:1 which allows for over 30psi boost pressure and RPM range beyond 8krpm.

The turbine wheel is larger in diameter than the stock TD05H. The larger diameter significantly increase the turbine flow and reduce turbine blockage in the housing compared to a stock TD05H turbine wheel. "

Any further info on the turbo apreciated.

go red!

With all due respect i would not upgrade from a FP Green to FP Red on a built shortblock. When i do change i will be looking at a T4Z or the like.

I'm stuck with the Green until next year hense my original question.

One of our local chaps here in vegas Ran the Green last year on his GSC 2.2, he posts here with the username: Nils.

He had a bit of fun with it but it was not the best on top end. He switched to the Red like everyone else did/doing.

So really your going to see a noticeable drop after 7K....like you would see on a stock 9 turbo after 6k with a 2.2L

The statement made on FP's site was for a 2.0L

Here's a graph of a green with a 2.3L stolen from the ECUflash area. Major boost taper on a stroker motor. Only 16 psi at redline.

The closest info i can come across is that the Green uses a T04E 50 trim compressor wheel. In which case i should be able to run a 2.2 up to 30 psi mid range dropping to 23psi at 7500rpm.

Nobody seems to know exactly what spec the Green is. (except FP)

What kind of boost control on that puppy? I'm inclined to say an MBC.

Well the thing about 2.2/2.3L Strokers is that they need to flow a lot more air so you should be more concerened with the size of the Hot Side rather than what the compressor can flow...

An engine needs to expel the burnt gasses on the exhaust stroke and if your hot side is a restriction it will choak your performance at higher rpm.


I am looking at going from a T3 .78 Hotside to a T3 1.06 Hotside for this very reason...

Yes, I was using a turbosmart MBC because my AVCR solenoid wasn't working correctly. Also, keep in mind, I have a 75mm tb, SMIM, and stage 3 head with 1mm oversize valves. I'm thinking the green is a little too small for what I need.

im not sure what kind of answer your looking for but from what ive seen with the green it looses alot of its steam after 7k and you may be able to run 30psi but without meth you wont be too safe with your timing maps. That motor is made to rev out high and that turbo is limited so not a good combo if you ask me

Knowing that you have a ported head makes that severe boost taper make more sense to me. I have still seen Greens hold decent boost even with a SMIM and 65mm TB. But making the Evo head flow better is going to make (obviously) everything else work more efficiently.
