Subaru Engine Conversion Wiki, Let's compile all the knowledge into one thread... Options

[Britain Smith]

I have been going thru several of the threads regarding Subaru engine conversions to learn about the different ways people are performing the installation. From radiators to CV adaptors, there are several paths to take. Lets try to compile all that information into one thread. Anyone can contribute and I will take the information in the thread and update the top few posts with the details.

Here is a list of 914 Subaru related Threads:

3. Renegage Hybrids (http://www.renegadehybrids.com/)
Don't really break down the adaptor plate seperatly on their website.
Includes Billet Adapter Plate, Custom 9" Flywheel, Kevlar 9" Clutch Disc, Stage Two 9" Pressure Plate

Some random images of adaptor plates, I don't know which manufactures.






- CV Joints/Output Shafts

There are replacement output shafts for the Subaru transmission to 914 CV joint.


There are the option to machine a set of 911 axles to mate up to the stock Subaru CV joints as shown by BIGKAT_83.
"The axles are 911. These are a large enough diameter to be machined on the transaxle side for a Subaru CV joint spline. This gives me a 911 large CV joint on the wheel end and the Subaru joint on the transaxle side. "
