1982 to 1991 Porsche 944 Service Repair Workshop Manual PDF
VEHICLE/EQUIPMENT INTRODUCTION:
The Porsche 944 is a front engine rear wheel drive sports car manufactured by Porsche AG from 1982 to 1991. Designed to replace the Porsche 924, the 944 shared the same basic platform but featured an all new Porsche designed 2.5 liter inline four cylinder engine, wider body, and improved handling. The 944 was positioned between the entry level 924 and the flagship 911, offering a more affordable Porsche with genuine sports car performance and everyday usability.
The 944 engine is a unique 2.5 liter DOHC inline four with a balanced shaft system that eliminates the vibration characteristics typical of inline four engines. Early models produced 143 HP in US specification, rising to 158 HP and eventually 228 HP in the Turbo models. The five speed manual transmission features a rear transaxle layout for near perfect front to rear weight distribution, with a rear transaxle.
The 944 underwent several revisions during production including the introduction of the 944S with 16 valve head in 1987, the 944 Turbo in 1985, and the 944S2 with 3.0 liter engine in 1989. The Turbo and S2 models deliver performance figures close to the contemporary 911.
