Gordon Nichols posted:Am I missing something here? I was always under the impression that a 912 and 914 engine were BOTH “Type 4” engines. The 912 had a stand-up fan shroud (like we’re accustomed to) while the 412 boxy station wagon car (with the same engine) had a “pancake” shroud to get everything under the floor of the car, like a Type 3 but a 2-litre engine.
The 912 was built from 1965 to 1969, and then a one year revival, 1976. The '65 to '69s had a 1.6 356 engine. The Type 4 was not produced until 1968 and started as 1679ccs. The 1976 912 brought back not only the 912 for one year, but also the Type 4 engine which had stopped being produced in Germany in 1974.
And more importantly for Bairedge, the transaxles in a 912 and Type 4 are different. A stock early 912 non-Type 4 engine puts out more horsepower, 102, than a stock Type 4, but it isn't hard to modify a Type 4 to put out greater than 102 horsepower.
IIRC, the 912 had a doghouse fan shroud, except for the 1976. The photo of the 912 engine that Bairedge is using is an early 912, non-Type 4, which has a doghouse fan shroud. If I needed an adapter for a 912 engine to a 914 5 speed transaxle, I would contact Kennedy Engineering in Palmdale as a last resort, only because I would sell the 912 engine to someone who has to pay for originality and then build/buy a hot Type 4.
