I rebuilt my T25 myself. Truthfully it wasn't that hard at all. Just need to carefully follow directions as there are a few little steps you might miss or do wrong if you're not paying attention. So far it's working just fine except it passes a little oil through the intake side. Not sure why unfortunately.

He will balance the rotating assembly for free if you buy the rebuild kit from him, or $25 if you just send it to him (can't remember if he sells T25 kits). Cleaning coked oil from the shaft and media blasting the wheels is included in the price.

The wheels are individually balanced from Garrett, and some rebuilders may say that is enough, but IMO, balancing the assembly is important on the small, high speed turbos we use. At 130,000rpm a small imperfection on an impeller can cause a enough imbalance to eat up the bearings in no time. That's my take on it.
The oil leakage porblem of my turbo started recently and it's not that serious. The compressor wheel and turbine are both in good condition. If I have marked the compressor wheel and turbine during rebuilding, is balance still very essential? As I'm living in Hong Kong, it's not convenient to ship the turbo back and forth.

Thanks for providng the URL of the rebuild company and their charge is reasonable. Just want to ask if they have good reputation? Also are they able to rebuild my turbo? Thanksl
