Does it need rebuilt? MHI Evo 3 16g?

[chanley talon]

Well i bought this MHI EVO 3 turbo cheap today. I was told it worked great and boosted great. But i noticed a few chips in the blades here and there and need some help deciding what to do next. Please look at my photo's.

Turbine wheel.

Definitely ate something...What is the shaft play like? If the shaft play is acceptable and there doesn't seem to be any other physical damage I'd try it and see what it sounds like.

I had bent some fins on my 14b and afterwards it honestly sounded like someone was blowing on a kazoo when I hit boost. It went from having no shaft play to a ton of slop in a couple weeks. Probably due to the in-balance.

If you do run it, definitely keep an eye on the shaft play cause you don't want that wheel hitting the cover and sending tasty metal treats into your engine.

The shaft play seems normal. It has a little side to side. But it appears to be missing a freeze plug also? I am not sure i can buy one or not?

Needs a new compressor wheel for sure. Rebuild kits are affordable and easy to do. There are a few write ups and videos that help a ton.

What about this missing freeze plug?

Those are oil, and coolant lines. These are just pipes that are held in by a bolt and two crush washers, if you don't have any I'm sure you can pick some up from Miller Imports for fairly cheap. No big deal, but as for the wheel it looks almost as if something ate it.. did this come off of a blown engine?

Well I didnt ask. I got two of them. One is a knock off.


Also there are no threads in that whole. It is for sure water.
I am almost certain it takes a freeze plug. Where can I buy a good quality turbine wheel and shaft and compressor wheel? I am willing to spend some money to make this thing work.

I would PM Justin here on the Forums, he does good work. Also that hole on the right is an oil or water line, and the left side stays capped just as is.

PM JusMx he should be able to help you out.

Check out Trader Greg for some parts. I bought a turbine wheel and few rebuild kits. I was very happy with quality
