I need a rebuilt kit for my turbo. I've see a few on ebay and wondering if that's a good idea. If not is there another place where I can get a rebuilt kit for this turbo? Also is this something I do myself. I wouldn't need any special equipment. Thanks

 

look at gpopshop.
I used their kit for all my turbos.

The ebay kit should do fine but I never had experience with them.

You will need a snap ring plier to remove the snap rings, and replace the journal bearings.
Look at this here

Its the same thing, but instead of a stock turbo, you are doing it to a t4 compressor housing. Same procedure. You will also have to get it balanced if you are taking it apart, unless you marked it before dissasembly and aligned it back correctly
