I have researched the 912E for about 17 years now and currently own two(986& 486).. The 912E is a huge portion of my customer base because so few people understand the car/engine.
The 912E uses the same longblock as a 1976 914. The camshaft used is the same spec as a 2.0 Bus engine due to the L jet EFI and lower CR of the engine from the factory. The realy special components for the engine are many of the EFI parts, and the entire exhaust system including heater boxes. We are currently having 100% reproductions of these being made from Stainless since originals are so shot out after 30 years. The flywheel/clutch/pressure plate/disc are all 914 parts 100%. The tranny has the SAME gearing as the 915 for the same year 911. The difference in the 923 gearbox is the input shaft, as it is a 901 unit. For this to work the intermediate assembly is different and that calls for special bearings. The 912E used a 14" wheel and a shorter tire to lower the gearing a tad for the less powerful engine that only made 76HP stock. The 912E engine was a "Sweep the floor" unit for sure. Of the dozens I have built (well over 100) no two have been exactly alike! None of them have an engine serial number on the case, only on the fan housing! |
