I currently have a BMW 2002 that I race is SCCA's ITB class. SCCA is starting a new Club Racing class next year called ITR and they are going to class the '78 to '83 SCs along with a host of other cars.

For those not familiar with SCCA Improved Touring classes the engines have to be basically stock but balancing/blueprinting is allowed, a .5 bump in CR is allowed and a 1mm overbore is allowed. The stock CIS would have to be used, stock cams, etc.

Suspension bushings are free, spring rates free, sway bars free. Bodywork same as stock. Stock brakes, pads free.

Min weight with driver is around 2650 lb (I forget the exact weight). There is more detail on cars classed on the Improved Touring forum. I suppose a PCA G Stock car would be pretty close in spec, about 100 pounds lighter.

Since the '78 to '83 look like they'll be on the same spec line, what kind of power could you get mixing components, such as early large port heads and intakes with later high CR pistons.

Am I insane for considering this?
