I've built up adapter plates from 5mm aluminium to fit TB's to a side-draft webber manifold. It wasn't easy, but, it worked evnetually.
In a RWD setup, dodging the water outlet is a PITA.

Where can I get some quads off the 20V?
What kind of things need to be done when installing the quads besides adapter plates?

I'm gradually working on an adapter for this purpose too - except I started doing mine in steel, and made a pretty big hash of it so far!

Installation sounds fiddley but not impossible. Im wondering about all the connections to the qtb and the tune side of things.
Can anyone shed some light on this for me?

I read that and it doesnt seem to have enough depth to it. Im looking for something more detailed.

You need six pieces of alloy - Two ~10mm plates and four 50mm diameter thickwall alloy tubes.
The alloy plate on one side goes onto the head - Use the gasket to work out the shape for it, it's pretty easy. For the throttel body end you need to mark it out very carefully to make sure that all the TB's line up exactly right with each other.
Take you time and make sure it's spot on!
With the alloy tubes, you cut them to the right length and then cruch one end in a vice so that it matches the oval shape of the inlet port end. You maye well have to trim a little with a hacksaw, etc, to get the right width.
Take a LOT of time to make sure it's all going to slot together okay smoothly.
Then get it welded up by someone very good with a MIG or TIG welder, then spend another couple of days dressing it all up with a file again.

I just use a dead stock fuel system, ie, the fuel rail bolts to the head and so do the injectors (though I use GZE ones) and then just connect up the fuel lines as you normally would.
I think I had to turn the pressure regulator a little, but it was easy to do.
