Thread: P11 vs B15 Clutch Master

Does anybody happen to know the difference between the P11 and the B15 clutch master cylinder besides the two having different part numbers

My clutch master took a poo poo on me so my car is out of commission. Spoke with GregV and said the P11 part is on back order and there are 30 B15 masters in the US.

Would I be able to use the B15 master in my '02 P11?

I just looked them up in the FSMs and they look physically different... So I would say nope. You might be able to get the b15 to work with modification, but not a bolt in affair.

werd. thank you kind sir

Here I will one up myself. Here is picture of b15 master from FSM for your reference.



And P11

Damper is built into the B15, while the P11 has a external damper. the b15 unit also sticks out about 2" more than the P11. I'm going to try to fit the B15 one on my P11.
