I know this engine has been used in the 914 chassis before, and it's an awesome alternative to the Porsche 6 conversion, but it's never been done with a Boxster/Audi transaxle. Here are a few pictures to get things started.
First, some rust repair around the "hell hole". All of the shiny or grinded metal is new material to replace the cancer spots...

(IMG:http://www.914world.com/bbs2/uploads_offsite/i180.photobucket.com-11979-1355114276.4.jpg) Mocking up the drivetrain... (IMG:http://www.914world.com/bbs2/uploads_offsite/i180.photobucket.com-11979-1355114276.5.jpg) Nothing ground breaking with the engine mounting cradle really, other than the use of the stock Boxster transmission mounting brackets which meant the engine cradle goes above the axles rather than below.

There's probably a thread here somewhere with these details, but where did you source the adapter plate, clutch, etc? What's the max HP rating on the Boxer tranny BTW?
Great work... |

We make the adapter plate and flywheel. The clutch is an OEM type Boxster clutch. Hard to get any solid "horsepower rating" figures on the Boxster 5 speed. It's actually an Audi 012 transaxle so you might have an easier time finding information on it's strength by searching the Audi world. From a size comparison, I would say it's components are along the lines of the 915 transaxle. Porsche used this transaxle in the 2.5 and 2.7 Boxster base models and say factory ratings of just over 220 hp so they should work well with this Subaru 6 cylinder which is rated at 230hp. We are working on putting 320-340hp through this transaxle in a Boxster using a Subie 4 cylinder turbo engine. |
