What engines were fitted to the 3.0 CSL?
The engine used in the first version of the 3.0 CSL was entirely unchanged from the standard 2,985-cc M30 inline-6 found in the 3.0 S/3.0 CS models. With an 89mm bore, an 80mm stroke and dual Zenith carburetors, this unit produced 180 hp (DIN) at 6,000 rpm and 192 lb/ft of torque at 3,700 rpm. The second version of the 3.0 CSL carried over this same basic engine configuration but the bore was increased very slightly to 89.25mm (for a new overall displacement of 3,003cc) and the twin Zenith carbureotrs were replaced by an electronically-controled Bosch fuel injection system. Horsepower increased to 200 hp (DIN) at 5,500 rpm and torque increased to 204 lb/ft at 4,300 rpm. Though these were identical outputs to the standard fuel-injected 2,985-cc unit found in the 3.0 Si/3.0 CSi models, the slightly larger displacement helped better suit the requirements of the competition version. The final version of the 3.0 CSL utilized a further enlarged version of the fuel-injected M30 powerplant wit
