3.0 to 3.2 Engine Rebuild
 

When it comes to Porsche engine rebuilds, I'm a virgin! (I have rebuild other engines though).

I'm going to tackle a 3.0 engine rebuild over the Winter, since I have found one broken head stud.

I have a few questions that I would like you guys to answer:

1. The vehicle (1980 911 SC) has run 101,000 miles, does this automatically mean new pistons/cylinders? Or do I need to measure a few things before making that decision?

2. Can I easily increase the engine displacement? 3.2 L or larger?

3. If I decide to supercharge the engine, can I buy pistons to suit the lower compression ratio? Any ideas on the relationship between compression ratio/boost level and power?

Regards

Mike

100k miles is not that much for there engines. You may find the pistons and cylinders still within spec.
