As long as your friend has taken care of his car and not flogged the turbo with high boost pressures or aftermarket BOV's that might leak boost and stress the turbo it should be just fine. Blouch has to take the turbo apart to do the upgrade. You can ask them to check the bearings and call you if they need to be replaced. If they are good, no cost. If they are bad then you can make that decision on the spot.

The turbo I'm sending for the 19t upgrade happens to be a deadbolt monster td04, so it already has some nice exhaust porting and coating. If it didn't, I would still pay the $95 for porting. Clipping the turbine wheel gets better top end power, but you lose a little of the spool characteristics. The porting work should increase exhaust flow into and out of the turbine which should recover some of the spool characteristics you'd lose from the turbine clipping. IMO its the best way to get the top end power while maintaining decent response.
