I used the kit from that source for Mercedes parts. So far it's looking like a local turbo shop could have professionally rebuilt it for not much more than the cost of the rebuild kit. I would definitely recommend checking what a local turbo shop would charge for a rebuild before buying a rebuild kit. They should be able to do T3/T4's in their sleep.

Keep in mind that "if it blows," your turbo may send metal bits through your engine. I hope you have a spare engine in addition to your spare turbo.
