Hey, new to site. I've been running a t3/t4 .63ar cheap ebay turbo for the past 2 years at 20psi. It's on its last legs and I want to upgrade.

I really want a gt3076r with .82ar turbine but thats way too pricy. I found a turbo on ebay which seem pretty decent. It's even ball bearing. A little bit bigger than what I wanted but I dont mind.

I'll be putting it on my mazdaspeed protege 2.0L It has 9:1 wiseco pistons and eagle H-Beam rods.

I drag race so I'm looking for something bigger to get me that peak HP in the top end.

Heres the link to what I found

Im open to suggestions on other turbos as well. I'd prefer ball bearing but i'd rock another journal bearing if it was the size I want.

 

thats a t4 turbine inlet. most likely way to big for your application. i use a gt3582 on my 2.2. it doesnt spin up till 4500 rpm but thats what i wanted. if you dont want that much lag they also have a gt3568 version with a smaller exhaust housing.
