Add ARP Head Studs
Add ARP Rod Bolts
Add Titanium Valve Springs
Use High-Flow CIS
Add Carrera Chain Tensioner upgrade
Add real 964 Cams

The 3.2L engine will have more HP, and more top-end, but lacks the peppy punch you will find in a 3.0L. Add that you will probably want a Motronic engine management system on the 3.2L that will add better fuel reliability, while adding complexity.

The 3.0L from an SC 911, when you use an early 70's era SSI setup that goes into a dual in dual out muffler, coupled with a short ring and pinion set 915, and you have one hell of a ride! Trust me as I know firsthand.

What does the 964 cam bring to the table on its own?
