Based on the new 993 Carrera 2 coupe, the 993 Cup 3.8 was developed at Porsche s competition department to replace the 964-based Carrera Cup 3.6 racer.

Aimed squarely at the 1994 Supercup series, it utilized a new 3.8-litre M64/70 engine.

This powerplant developed 310 bhp at 6,100 rpm, 40 more bhp than the earlier 3.6 Cup engine, and gave the car a top speed of 280 km/h.

The new engine had a rev limit of 6,900 rpm, but as it utilized many valve-train components from its sister RSR, was capable of turning safely as high as 7,900 rpm.

This meant that the engine was low stressed for a race engine and incredibly reliable.

The new 6-speed gearbox has very short shifts and was also enhanced for more reliability with steel synchromesh rings.

The 3.8 Cup engine type number is M64/70 and gearbox type number is G50/30.

The upgraded six-speed G50/30 manual transaxle had 40% limited-slip.
