Why? The 20R is about the only thing I can think of that has as little grunt as the stock Zuk 1.3. Now, if you took a 22R and put the 20R head on it, the you'd be talking. :grinpimp:
Mods? Um, radiator, starter, clutch, tranny/tcase (I see *NO* reason not to run a toy 5-speed and Tcase(s).) and, um... motor mounts? Pretty much the standard motor-swap stuff, but then again, I've never actually tried or seen one of these swaps, so I don't know.
I do know that you can run a carbed toy motor on VERY few wires, and that some dicking with the Toy carb can get it to nearly run inverted. So at least the wiring would be easy.
