Which motor does your Jetta have? Some of those Jetta's were pretty zippy.
Both are the 2.0L naturally aspirated version. Nice torque and fun to drive, but not super powerhouses. They do well with a turbo, though. Current plan is to check out the spare and rebuild whatever is needed then use it to get the car running. The motor in the car has a big cam in it and a chipped ECU, so I will put that head on the spare to add some snappiness but it still won't be a monster.
Long term I will rebuild the damaged motor and decide if I want a lot more power from a turbo or not.
