In Need of some assistance!, 914-6 conversion! Options

[Mr_Chu]

I currently have a 74 914 2.0-liter. I also bought a 78 911sc recently. What I plan to do is to drop the 915 tranny and the 3.0 liter SC motor into my 914 to give my baby more of a punch. I know I have to do the suspension, brakes, yadda yadda.

But here's the problem I'm having. I talked to a porsche mechanic here and he claims that the 915 tranny won't work in the 914. Is this true? Or is he blowing smoke? I know that the V8 conversions sometimes use 915 tranny's. And if I use the 915 tranny, do I need a rebuild? About how much will it cost? But anyway.. I have more questions to follow.

Another problem I have is how to fit the motor in the 914. Does everything bolt in? Or do I need to cut and weld?

The wiring is another nightmare I am having right now. Do I need to re-do ALL of the wiring in the car?

This project is giving me headaches! Any comments or suggestions will be appreciated!

If you plan on using the 915 you need to flip the R&P.

The 915 will work in a 914. It just needs the R/P flipped to work correctly.

the 3.0 will need some parts to fit correctly in your car. You will need:

-6 Motor Mount (Richard Johnson's is the mount of choice)
-6 Sheet Metal (lots of options there, steel or fiberglass)
-6 Oil Tank (factory are preferred, but others use aftermarket)
-6 Heat Exchangers or Headers
-6 Oil Lines

There's more, but that's off the top of my head.
If it's CIS, some cars had to modify the engine/trunk firewall with a notch to fit. (my 2.7 had that done)

Good Luck.
