The biggest difference between an american v8 and a Porsche is that the Porsche has good parts to start with. Also the Porsche uses some one time bolts, like the connecting rods and flywheel ones, that really means ONE time. Once you tighten them up they are history. You can get around this by using Raceware or ARP bolts but you will pay for it.

The other big differance is Porsche uses 10 parts for every one in a american v8. There are parts, more parts, and more parts, you will not beleive how many parts they could put in a 6 banger. No magic, just keep track of where they go. The book is a great help.

I would also strongly recommend Bruce Andersons book on Porsches as well as the factory manual. Take plenty of pictures yourself as you take it apart, you will not regret it.

The basics are exactly the same, american v8 or porsche. Measure everything. The tolerances for Porsches may be tighter than american ones, thats why they get more power per cube. The materials are like typical racing parts for american v8s, no need to improve on them. Unless you go for over 400 HP you will not need things like Carillo rods, the factory ones are good.

By the way DO NOT GO FOR over 400 HP. Porsche engines are air cooled, that limits them to about 320 HP for a reliable engine. There are people getting over 600 HP out of air cooled Porsche engines, they all have a nice, pretty coating on the exhaust system, thats consists of melted piston material. You can do this to, but not for long. Thats the scoop from a PORSCHE ENGINEER that worked on the design. Water cooled heads are needed for more power. I am just repeating what he told me, and I beleive it as I have personally seen the results.
