adapter plates for gearboxs
Discussion
hi there does any1 know how to make there own gearbox adapter plates i know that practical performance mag did an artical on it in issue 17 so if any1 has got issue 17 that they could copy the artical on the adapter plates for me would be a big help but if not any info on adapter plates would be a big help many thanks dean
Its not that complicataed in theory...putting it into practise can be tricker though.
Just make a template of one bellhousing bolt pattern, then the other, ensuring the input shaft spigot is EXACTLY in the centre of both.
Translating that onto steel or aluminium, using as many fixings as is possible. Chances are input shaft may no longer be long enough then to reach the spigot bush in the crank, so that will need addressed too.

You can either machine down the engine side of the bellhousing or the gearbox side, whichever is easier, if you have a removable bellhousing it may be possible to find an alternative bellhousing to convert to what you need.
For example the Borg Warner T5 box used in TVR's has belhousings available for the ford pinto, the Rover V8, the TVR own engines and the cosworth YB to name but a few
Whats the project?

well basically i was thinking of using the alfa v6 and mating it to any type rw drive gearbox sumting like the t5 but it useful to know these things for future projects see i don't like auto's and if i can change the gearbox then i will i would like to use a bmw v12 for something but the auto box puts me off i am building a locost at the moment and as it stands i am useing a nissan 200sx s14a turbo engine in it but i am now think of the alfa v6 because of the noise it makes
I have designed these adaptors before and the difficulty of the task shouldn't be underestimated.
The most critical element of this is having accurate measurements of the bolt spacing and most importantly of all the dowel hole positions. After that it is a case of packaging a clutch, flywheel and release mechanism, and designing them so that everything works properly. Component selection is of course critical if the project is to be a success.
I don't think it is really going to be a good use of your money to do this work, stick with a proven system which though it may have imperfections, actually works. A Rover V8 with 77 mm gearbox isn't that bad, and spares are cheap and plentiful. This is not something you can say when you make your own custom parts.
