I'm replacing/building an engine for the Cayenne and need to get a hold of some technical data. I purchased a "shop manual" online and I beleive it is just a reprint of the factory stuff but it doesn't have any technical information such as torque specs for some things,main/rod bearing clearances, bore sizing, acceptable standards, service limits, valve spring installed heights, crank end play specs and all that good stuff that go's into a build.

Can anyone help me out or point me in the right direction? I prefer pdf's but it doesn't really matter

 

Did you ever find these? I might have the information you need from Porsche on rebuilding the 4.5 heads. Let me know.

 

I hope this will help you. If you need some more, let me know, I have all mechanical manuals.

Those are the manuals that I have, I might just be missing it in the 10k pages.... im still taking a look.


@Renaissance Man, I will shoot you a msg shortly, I want to make sure I'm not overlooking anything.
