I have been doin allot of research on this thing---do many guys actually use it???

Mr. B at HPH recommended that I go with the B.I.P on my tranny rebuild.

I did it on my current trans as well, after seeing how my previous 911's trans liked to eat bearings. I'm not totally convinced that it's an essential upgrade, but I had the part in the garage and got it at a deep discount so I figured it sure wouldn't hurt. An added plus is that the -6 conversion throttle bellcrank mounts up nicely (i.e., factory-style).
