There is one nuance tho, specifically with the Model S (not sure about plaid). The way the Model S motor is laid out, it is often more advantageous to fit it backwards into conversions. This should be fine, except the motor driven oil pump is meant to run mostly forwards and long periods of running it the other way cause problems in oil flow and might cause pump failures too. So there is a aftermarket oil pump that fixes this problem.
