Boxster transmission adapter plate, Relocated starter Options

[r_towle]

Guys,
In response to another thread about subarus, someone posted a link about a shop in AZ that is making an adapter plate kit to bolt up a boxster transmission to a Subaru motor.

Wondering if he sold a kit, or just did all the work, I reached out to him.

He does in fact sell a kit which requires milling out some of the bell housing, but then you can mount a starter.

Assuming much of the flywheel and clutch would not work, this might be a good place to start for someone who races, wants a more modern transmission, a cable shifter, and would like to remain all Porsche....

Naro...

Looking at the specs in PET and online, the Boxster and 964/993 clutch disks are teh same diameter. Both cars use a dual mass flywheel. But the Boxster uses a push type clutch, and the 964/993 uses a pull type.

I don't have any of them here, but I suspect the bolt pattern is the same for the pressure plate attachment. So IF you could bolt the Boxster pressure plate to the 964/993 flywheel, then there is no custom clutch parts needed. But you still need the adapter plate for the trans, and a place to mount the starter. The adapter plate may make the engagement of the pilot bearing a little short, and the throwout bearing stroke a little longer.

I would use the aftermarket racing flywheel to eliminate the dual mass setup, and use the aftermarket clutch throwout bearing that incorporates the slave cylinder into it. A spacer could be made the same thickness as the adapter plate for it.
