As above really, if you have the spare cash to waste on it then fair enough, I think you will be rather disappointed with it though. Even with 2wd they are not a fast car, the extra drag the 4wd system will give will make it slower.

Your best bet will be to sell the engine on again and get yourself a 2.0 zetec, turbo or throttle body it and it will be good fun and will fit with next to no modifications to the shell. The money you will save on fabrication can be spent on the engine and better suspension / brake setup.

There is a reason the v6 engine isn't transplanted much, because it just isn't worth the hassle!
