914 2.0 GA Engine/ Sideshift Trans in a 912?
I have a newly rebuilt 914-4 2.0 GA engine and Sideshift Trans for a 74 914.
Is this easily put into a 912?
Are there any issues to overcome (obviuosly this a type 4 style engine).
What is required to do the conversion? Any issues with the shift linkage?
Electrical Components?
Will it easily bolt into the Chassis?
Oh.. and this would be a 66-69 912.

Since the 76 912E came from the factory with the GA Type 4 engine, installing one in an early 912 is no problem.
My 69 912 has a 2.4L big bore version of the GA 2.0 out back. The engine tin is out of a 76 912E although I think that the original tin "could" be modified to accept the engine. The distributor is the same for the 2.0L and the 1.6L so most of the electrics are the same too. I use a CD ignition box from an early 911 but a MSD box is the preferred upgrade. Getting the fuel injection to work might be the only problem. This is easily solved with a set of Weber 44IDF carbs. The engine mounting is different but again, the 912E used the set-up so the parts are out there.
As for the trans, I'm sure that you'd have to use the shifter out of the 912 you have but that will bolt up to your tranny with minimal effort as all early 911/912 and 914 cars used the same gearbox. It all just needs to be spun around for use in the rear engined car.
The best part of the T4 engine swap is that everything that was impossible to reach in the 914 becomes very accessible once the engine is flipped around. The timing hole is right at the back of the engine as well as the oil filler, alternator and belt, etc.
Plus, with the extra hp, the car will haul ***. I guesstimate my 2.4L to be making around 140-150hp which is 911 power from the same era.

The Porsche Type 4 engine was actually a little different than the VeeDub version. The engine serial numbers on the Porsche engines started with GA. I don't know what letters VW used. The heads, I know, are quite different on the 914 engine, as for the case, anyone know?

GA GB and GC were 2.0 motors for the 914 and have specific 914 3 stud intake heads with bigger valves than a 2.0 bus motor, which has 4 stud intakes like all the rest of the TypeIV's. The GC did not have the second oil pressure relief valve installed. All had fuel injection and FI cams.
