or just use an Audi 2wd transaxle, same as they do in the boxster. They come in many flavours,

We have an Elva build thread. Look at project cars updates on the Classic Motorsports site.

Is there a handy website where I can peruse various VW transaxle gear ratios?

I've always wanted to know, do you need to flip the ring gear if you use the gearbox inverted like the Hewland gearboxes?  Is the reason to flip the ring gear solely to keep the input shaft above the diff for the flat engine applications?

Looks like I am going to need a couple of early VW axles to cut down and spline. Anyone either have some, or know if I would be better to start off with new ones. While I would rather start with new, so many of the VW parts are cheap crap.

Maybe check the technical section of TheSamba.com  Pretty much largest aircooled site.

You flip the ring gear if you're changing from the stock rear engine configuration to a mid-engine one because turning the transmission around creates a one forward/four reverse gear situation.

Is that just to keep the input shaft above the output, as in the "stock" location?  If you were to invert the gearbox (flip it upside down) then turn it front to back, wouldn't that keep it as 4 forward and 1 reverse and not need to flip the ring gear?

or use a reverse rotation engine, some Hondas run the other way

Flipped you will run on the wrong side of the ring, think any 4x4 front end that is not high pinion. Flipping also could create some oiling issues.

Me?  If I go ahead with this, very much no.

Correct, but doing that also changes the height of the engine from the ground, too. You may or may not want that.

so why use an old trans that needs modification when modern VW audi 2wd stuff would work?

Because they very specifically won't work for what I have planned.  Cost, weight, complexity, all of that is not something I want for this project.

I still need to sit down and check gear ratios and all, but things are looking good.

Nice.  I should be able to use that to figure out what I want to do.  Of course, there might be a possibility I won't be able to use the ideal trans for it.

That's really cool.  Looks like someone took a drill to a solid axle backing plate.  Is it a aftermarket solution or some modified stock pieces?  Looks aluminum so should be fun If you have to recreate all the holes.

A swing axle Type 1 transmission can be run upsidedown. A lot of mid-engine rails go about it that way. I've been out of the ACVW game a while and forget why they don't use the IRS transmissions upsidedown.

I have a bad habit of holding my projects pretty tight to the chest until I'm ready to start moving on them.  Also, still doing math to even see if this will work. 

Stay tuned, I guess?
