There are a host of things that can be done to improve the 930 engine. All of the above listings are tried and true. Typically a slow and incremental approach is better than doing it all at once. I have been involved in far to many truely nightmarish scenarios where owners try to do it all at once and get completely screwed by the tuner or mechanic.

I do have to dissagree about the cams. SC cams alone can produce more off-boost torque in a 930 3.3L than in the 3.0L N/A SC engine they came out of. This is the first thing I noticed on my engine, and the dyno told the tale. Cam and ignition timing are HUGE contributors to improved off-boost performance. It's not just the cams but the proper tuning of the system. Just tossing cams in with the same stock settings is not optimal.

I can set you up with a light weight free-flowing muffler. Check out my website for a few options.
