Design
Some of the M106's upgrades over the M102 are from the M30B34 version of the M30, which was also released in 1982. These upgrades include Bosch Motronic engine management and an increased displacement to 3,430 cc (209.3 cu in). Another upgrade over the M102 is that the compression ratio is also increased to from 7.0:1 to 8.0:1.[1][2]
Peak power output is the same 185 kW (248 hp) as the M102;[3] however, it occurs at lower RPM,[2] using 6 PSI of boost.[4]
