Yeah I know cheap is relative, ain't many such beasts when talking Porsche's. I am going with the 915, which I know would buy me a years supply of Haggis and single malt. I do not want to have to do it again, I don't want it to come apart again and lock up the transmission and become known as teener bopper
as well. Getting too old to suffer that potential pain when doing something hopefully better works.930 is more than my 3.2 would need.Blocking off first etc would surely lead to more clutch woes and may not protect the pinion.
