911SC Turbo Conversion?

Hi all,

Got a fellow Porsche friend with a nice tight 911SC who wants to turbo his motor with a low boost setup.

Any of you guys done this before?

The 3.0 motor runs 8.5:1 C/R, so I guess it should be fine with approx 10psi boost using a bolt on setup?

Got a few questions:

1. Would 930 style headers bolt onto the SC motor?
2. What fuel enrichment options are there for such a setup? I've heard no extra fuel mods for low boost?
3. What about ignition timing for this setup? I've heard stock ignition timing for low boost?
4. What should one do to strengthen the motor? Aftermarket fasteners/studs?
