I just found out that there may be a "problem" with using the 3.2 L Boxster motor. The problem is not with the motor itself but with the ECU. The ECU for the 3.2 motor is different than the ECU for the 2.7 motor. Apparently, in order to use either motor they need to deactivate the engine immobilizer on the ECU, and there may be a problem with being able to do this on the 3.2 motor. We are waiting to hear from the company they use to do this to see and make sure it can be done. I will update everyone when I know.
