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...

I owned a collision/resto shop for 18 yrs. I understand the need to be sure things work and are done properly simply for liability sake if nothing else.

If the 20k included the transaxle, axles, hyd. clutch parts, shifter stuff and materials I guess you could drive that cost up there. Understood.

My assumption was you had the transaxle and wanted mated to your engine. That's actually the easy part in my opinion. Much of the project could be done by you to avoid a huge additional cost like axles and shift stuff. You know what they say about the word assume... (IMG:style_emoticons/default/smile.gif)

sorry, didn't mean to insinuate you don't do things right...that came across wrong, my bad. I just know custom work takes tons and tons of time, especially if you have nothing to go by and you're doing it for a client. I think if we are all honest with ourselves about the work we do, we would realize we spend much more actual time between research, trial, error, experimenting, installation, testing, etc than we would ever admit. For example, I've probably spent 50 hours just researching this already!! If I were a business, I would have to bill the client for it...

Labor did include trans tear down/rebuild plus a lot for the hydraulic clutch system design and install - lots of fabrication here especially for the pedal cluster which needed to be completely modified/redesigned. Seems that the output flanges on the trans are not compatible with the CV's, so more machining work. Labor list of things is almost a page itself...lots of stuff...

To be honest, not sure how much of this I could do myself. I don't weld, I don't have fabrication equipment, I don't have a good way to drop the engine/trans or a bench to work on all this. and i am certainly not tearing into the transmission. I can do a lot of basic replace/repair stuff, but not fabrication or heavy mechanical work.

So...looks like for now i might go with the Velios 915 that's been sitting in my garage for a year...maybe if the car runs well for a year or so I would start thinking of going the Boxster Trans route.
