3.2 Rebuild & Modify Thread

I'm restoring my '84 911 3.2 and building it back up as street tuned turbo. I figured I'd start a thread on the engine rebuild as this is my first air cooled rebuild and I could really benefit from your expertise. The engine has 130k on the clock, has good compression, and seems to be in good shape overall.

The goal of this build is to refresh the engine and strengthen where needed. I will be running about 7 psi of boost through a custom turbo and standalone ECU. My goal is about 320hp and a 7k redline. Key parts of the build plan:

- (hopefully) reuse the cylinders and pistons
- Pauter rods
- Aasco valve spring and titanium retainers
- Regrind cams to 964 spec
- Twin plug heads w/ coil on plug
- ARP head studs
- Patrick 60-2 lightweight flywheel
- ECU Master Black ECU

I have a separate thread HERE where I will detail the development of the turbo system.

The rust repair, body work, suspension, etc. are all happening in parallel so this isn't going to go very quickly...
