There are a ton of "single use fasteners" inside these engines that are never supposed to be reused, there are very limited sources for piston rings and all bearings, almost no oversized units to compensate for worn crankshafts or cylinders (which cannot be overbored), so if your cylinder liners are out of round (which they probably are), you are in for $4-5K just for new liners at a minimum. If your piston skirts show wear, you are going to need new pistons, probably aftermarket units. You're are going to need Porsche cam retention and timing tooling, Porsche RMS installation tool, Porsche piston wrist pin tool, etc., etc. Some of these tools cost $500 to $600 each, and rentals are few and far between. There are very few areas where you can (or should) cut costs rebuilding one of these engines, which is why quality rebuilds from professional shops often top $20K.
