My car is running great after the CIS to ITB EFI conversion, but I'm not getting any younger and the engine and transmission have almost 72k miles so I decided to rebuild my engine and make it even more of a hot rod.

After talking with Al at x-faktory and Don at Don's Autowerks, I decided to go with 9.5:1 92mm JE pistons, 92mm Nickies cylinders, MFI S-cams from Web Camshafts with ARP studs and hardware throughout the case (not just the head studs) and use Ollie's Engineering for the case, crank, rod, and flywheel and Craig at G2 for the heads and cam towers machining work.

Before starting and at Al's recommendation I bought Wayne Dempsey's book "How to Rebuild and Modify Porsche 911 Engines 1965-1989". After looking through the book, I also bought Wayne's "101 Projects for Your Porsche 911" which has a detailed description of how to drop the engine/transmission out of the 911. Both books are available on PP (not a paid spokesperson :-)).

The following are some photos of the drop and disassembly process (not all as I took many, many photos to have a chance of putting this Swiss watch of an engine back together).

Must have tools:


I removed the ITB EFI to keep it safe in the trunk and I removed the back bumper to make more clearance for the engine before I dropped the engine/transmission:






An important note: the yellow "foot" I used with my floor jack to drop the engine/transmission depends on the weight being balanced on the floor jack. The above photos show the engine with the muffler removed, but the muffler must be in place (if only loosely attached) to get the weight balance correct so the engine/transmission will drop down level. I initially tried the drop with the muffler off and the engine/transmission was nose heavy at the transmision end.
The yellow "foot" worked great at holding the engine/transmission steady and I was able to safely drop the engine/transmission by myself (on PP it is P/N PEL-PW-2563 and it is called "Engine/Transmission Removal Jack Adapter Tool, for 911 engine with sump plate").
