Thanks, a lot of good info there. I was just looking at used Boxster prices and they have dropped so low that, if your 2.5L does die, it would be about the same cost to buy a used low mileage 2001 S as to do a motor swap with a new motor.

The 2.7 will need to be adapted for the throttle cable and the car will need a DME/ECU upgrade.
