Bruce Anderson has what I believe to be a typo in his latest 911 handbook in that there are 2 M64/22 engines listed, my references are solid thru '95 but spotty after that soooo......

Can anyone confirm or correct the following data?

• '96 on M64/20 is the ROW 3.8 Carrera RS w/ 51.5/43.5 valves 43/39 ports
• '96 on M64/21 is the ROW 3.6 Carrera(manual trans) w/ 50/43.5 valves and the same ports as M64/20
• '96 on M64/22 is the ROW 3.6 Carrera (tiptronic trans) w/ 49/42.5 valves and the same ports as M64/20

Is there an M64# for a ROW increased output 3.6 Carrera which uses the RS cams?
