While musing on another forum about an RS200 style drivetrain (mid-engine, longitudinal, AWD) the thought of using a relocated subaru transaxle with a fairly simple transfer box (cobbled out of $20 worth of e-bay circle track quick-change gears in a machined housing) was batted around. The center differential is integrated within the Subaru box and various torque split options, 50/50, 60/40 etc are available. Similar setups could be had using Skyline, Jeep or English Sierra 4wd setups but the Jeep stuff will have funky gearing and a fairly crude center diff, the others might be challenging to source parts for in North America.
The "Tim" referenced in the bad sketch is Tim from the RallyAnarchy board who crafted a similar transfer box for his bike powered Honda 600 LeMons car.
With some careful packaging and part selection you might be able to shoehorn this into a Lotus 23ish body. You'd have some tough packaging constraints in the footwell area though, might be able to use a compact diff out of an ATV or similar.
The RS200 and the Veyron are where I got the idea for having the trans in the tunnel which is why I chose the skyline drive train. I wanted to use a sierra 4wd gear box but they are very rare compared to a Skyline box, but they can be had for between 500-1000 shipped on eBay. I'll have to look into the the Subaru transfer box idea but in general Subaru drive trains are a bit more than I wish to spend but if I can do it for cheap that might be the way to go.
As far as the body goes, I drew up a KTM looking car about a month ago that I wanted to use but now I'm thinking along the lines of a 23, 30, or even something based from a Ford p68. I haven't gotten very far as far as what it will look like. The big thing is trying to figure out the packaging first because the Skyline gearbox is by no means a small box so I'm still considering other options including a awd CRV gearbox with a rotated transfer box, but I'd really like to figure out the skyline box cause its so bullet proof. Still have a lot to figure out before I start buying parts.
