Hi guy.I have just finished working with my STI and the outcome is fantastic.I have installed a Greddy T67 25G turbo kit with FMIC of the same company.ALso have walbro 255 lt fuel pump Greddy E-Manage,Profec B Boost controller,External Wastegate Type-R Greddy and a lot of other mods.I am boosting right now around 22 p.s.i. wich is 1.53 Bar.Does anybody knows how much h.p. can i work with stock Internals on a EJ207 STI Ver.8?Thanks.....

 

I think the pistons (hypereutectic cast on more recent EJ207 AFAIK) might struggle with that if the car is driven hard, in hot weather, on track, and/or for high mileage, but there is one way to find out

How does the turbo spool up? Is this turbo a hybrid of a T67 compressore and a TD06 turbine?

 

A greddy t67 is indeed a td06h turbine with 25g comp wheel. Option of 8, 10, 12 or 14cm^2 housings I think.

450 bhp is a realistic target

 

Actually beryllium this is what i have in mind.I believe that with correct mods and....boost 450 Bhp seems realistic.Does anybody have any idea how can i upload some Pics of my project here.
