Craig,

NO, the 911/01 on your bench is significantly different from the 901/13 in your 911. The most important are the gear ratios and the clutch actuation. I wouldn’t fit the 911/01 to your 911 unless you converted to the 225 mm pull-type clutch. Even then, I would change the gears from your 901/13 into the 911/01. Probably both transmissions have the “simplified differential” issue.

I realize you have a 911/01 on your bench and that you want to be able to do an in-and-out swap in a weekend. There are some serious reasons why this is inadvisable. Let’s find you another 901/13, get it serviced and then you can have a successful swap weekend.

The other option is to rebuild your 901/13 in a weekend. Are there Porsche friends that can help you? I can do this repair between track sessions; it isn’t difficult if you are prepared.

The raison d’etra for a Type 911 is to use the 225 mm clutch.

Again,
How about answering the other questions?
The more info, the better we can help.

Best,
Grady
