I guess I have been unaware of this...

The guy selling them has done some nice work. I remember a suby powered Boxer that was quite nice.

^ditto, great deal on those axles, oh so tempted since I happen to have a Boxster transmission as well....

Would that bolt up to a Porsche 6 (aircooled)? Boxster trans I am talking about.

Ask him. The thread below is his work with the Boxter. He did a couple of awesome 914's too.

IMO

you have to spend a lot of money to make a 914 drive as well as a nice used Boxster S.

I started to draw something up [on phone, cannot find thread I started]

Clay is working on his version and more than likely get his done 1st.

I just came in from the garage where I was working on a wooden mockup of the adapter plate. I had to stop because I let the magic smoke out of my dremel trying to cut the center out of the wooden mockup.


Here is a picture of the adapter plate dimensions.

This was a bitch to create. Lots of time researching it, and lots of time testing and combining the drawings. I have made 4 separate wooden mockups. I had one hole slightly off on the last one.

And I still have to make the cutout for the DME sensor.

I am going to go try to make the first one later this week. Wish me luck.

Mueller... if you want to try it, go for it. I have to go borrow some time on a Bridgeport to make this.

For Reference, here's the G86 bolt pattern diagram I found on the internet.

Once I make the plate, I am going to pull the engine off the stand and test it.


Honestly, I wouldn't go to the trouble if it wasn't a 6 speed, or I could flip the ring and pinion on a G-50 gearbox.

I am adapting a G87 trans from a Boxster/Cayman S to an air cooled engine (from a 993 but with 964 inlet manifolds to fit under the engine lid).

I will use a flywheel from Kennedy Engineered Products and found that the adapter plate must be 20mm thick.

I started by printing a 1/1 scale drawing of the G86 Porsche/Audi bellhousing bolt pattern available at https://grabcad.com/library/01e-audi-transm...-bolt-pattern-1

1) I noticed that the above mentioned drawing does not include one fixing hole which I will use with the G87 trans . I will mark this hole and drill it when I get the adapter plate and check the mating of the trans to the engine. I will then update my CAD file.

2) These drawings still do not present the cutout and fixing for the hightorque starter. I will post the final drawings when I complete that detail.

3) I did not consider the cutout for the DME sensor because I am not using it . I am running the engine with a programmable Engine Management System (with wasted spark : https://en.wikipedia.org/wiki/Wasted_spark ). I am not going to add the detail for the DME sensor to my drawings and CAD file, but that is presented by Clay Perrine at http://www.914world.com/bbs2/index.php?sho...204.0&st=80 (see Post #91).
