I just finished rebuilding my turbo. It is a Garrett T3 with an Air Research compressor.

Before you take the turbo apart score the compressor to back-plate and the turbo to oiled section as these will rotate 360 and can go back any way you want.

The job wasn't too hard, but I did break 1 encapsulated carbon seal by assembling it wrong, and Ron broke another installing it.

I used Ron's Turbo Service for the parts and balancing (free).

You need to make sure you get the T3 encapsulated carbon seals.

I have a tool that was made by a friend on this site that allows you to put the carbon seal in without damaging it. You need a big socket on the other side when you are tapping the new seal in.

You will need some special snap ring pliers to put the snap rings back in that hold the journal bearings in.

You can use the shaft and turbine from another turbo and have it balanced.


Oh, yeah. You will want to completely clean your intake manifold and crossover. It will be full of the the nastiest stuff you have ever see. On Shop Forum it is called "devils food cake". I dug about a pint of the stuff out of my intake and i bet that stuff is capable of killing engines. To prevent future devils food cake you your EGR vacuum line might spontaneously injest a BB. Mine did that, and somehow a plate got installed across the place where the exhaust goes into the intake.
