Single VS Quad throttle bodies + injector position?

A mate is interested in setting up a 1600 with EFI for khanas/rally. Of course it's a budget thingo. Lots more HP for no $$$ as per usual. I'm currently looking into throttle bodies (TB) at the mo. The cheapest usable factory throttle body is a 40mm unit off a hyundai excel. They are around $50 each, so looking into the different in performance between singles and quads makes a lot of sense to see if we can get similar results with a single TB. Some tech advice on plenums would be nice too. Is there a good EFI site somewhere with a writeup about these things? Also, I'm interested in figuring out the difference between injector positioning in terms of valve back VS throttle face. Any ideas would be great. Pete
