I do'em for a living. If you are pretty mechanically inclined then go for it. If not don't think about doing it. It is a rather complicated deal and is made harder with the turbo and different axles. On the N/A engine you can just about jack the engine out of the car. The turbo hits the pass axle and it leaves you about and inch shy of making the job a WHOLE lot easier.... Get a water pump done at the same time. Cheap insurance.
