I've checked Kinugawa's website and they only list Turbos for Evo 9. Don't they fit Evo 8's?? Why are they only listed for Evo 9??

I do have an Evo 9 Turbo on my 8. I want to upgrade the turbo but don't want to spend too much like $2000ish. Do you guys think a 20g or a 25g turbo is a good choice for me??

Is there like an Evo 8 install kit for these??

so we come back to the other question

I do have an Evo 9 Turbo on my 8. I want to upgrade the turbo but don't want to spend too much like $2000ish. Do you guys think a 20g or a 25g turbo is a good choice for me?

Here are the other stuff I purchased but didn't install yet
GSC S2 Cams
HKS Cam Gears
MAP Beehive Springs
MAP Ultimate Duty Headstuds
ITM Revised Lifters
MAP High Performance Valves
Walbro Fuel Pump
FIC 1050cc Injectors
AEM EMS
MAP 02 Housing with External WG Dump
3'' Exhaust

 

If you already have a 9 turbo on your car then you have the 8 to 9 install kit...You should be good

 

but is the 25g a good upgrade over stock 9 turbo?
how much power increase would it yield on some psi?

 

That thread i linked, will soon have answers to this question. No one really runs these turbos. I'm just as curious as you, but I would choose the 25g turbo with a billet wheel and 11.5 hotside and you'll make some good power I would imagine

 

when I choose the 25g on kinugawa website, it won't let me select any options such as 11.5 or billet wheel
or am I blind??

I'm gonna say blind, just takes a few trips around their site to find. So just partially blind They're separate options

but i just realized the 11.5 wont work with the 25g I think....

 

The 9 is the only turbo with the compressor cover large enough to fit upgraded wheels of those sizes. You can put a nine turbo on eight so they are compatible, just don't use your evo eight turbo outlet pipe or waste gate actuator

 

thats not true. 8 turbos can accept any wheel that can fit in a 9. I have actually been quite confused why no venders do upgrades for 8 turbos. big hole in the market if you ask me. big wheels have been installed in much smaller covers than 8s for years

Jerry i think what he means is that you can't upgrade the evo 8 turbo's because the kits usually come with anti surge housings too.
I've only found one company on ebay that sells 20G anti surge evo 8 housings.
I actually bought a billet 20G wheel with anti surge housing to find it didn't work on my evo 5 turbo So i scored an evo 9 core housing off a friend and i'll put that together.

I agree that the Evo 8 turbo/compressor upgrade market is lacking, i tried convincing the company that made the 20G wheel i bought to make an evo 8 anti surge housing.
I still haven't had a chance to test it yet, work comes first.

Cheers, Mike

 

So a 20g compressor wheel will fit a Evo 9 compressor housing? ...I thought 20g compressor wheel required a 20g compressor wheel housing.

 

Yes from what i have recerched, but the evo 9 compressor housing needs to be machined i believe.
