I was just wondering how much i would be looking to gain with putting the evo 9 turbo on my 8 i have already added the ported and polished 10.5 and i made 333hp last week. I searched and i really couldnt find a straight answer is buying the turbo and putting it on worth all the work?

 

Maybe 20hp depending what octane and psi your run.

 

The only difference between the 8 and 9 turbos is the 10.5 hotside (i believe).

If you already ported yours, there is really no difference.

 

yeah that is what i was thinking also

 

no... the 2005 evo 8 mr has the 10.5 hotside...the ix has the 10.5 hotside also but also has a larger compressor wheel and housing ...

 

i made 347 with nearly the same mods as you on a dynojet with pure 91 oct eith the evo 9 turbo on an 8

 

oh ok thats what i was wanting to know so i could see about 15hp to the wheels by puttin the evo 9 turbo on my car

 

what was your psi i only had 21-22 on my stock crappy bov

i was also on a dynojet when i made those numbers and it was 99 degrees

 

Give or take a few. But that is the general area. Good luck in what you decide.

 

^^9 turbos don't have a bigger compressor wheel over the 8's
