So this is something I've not come across before. Has this been tried before? The only downside I can see is if there is enough contact on the water pump pulley, and if it would work on a crate engine Focus Zetec engine?

Zetec blacktop reverse pulley kit, mk4 escort xr3i, rsturbo, cvh

If its going in a kitcar you may not have room for the alternator there.

.........and where can you fit the engine mounting brackets?

Sorry, just realised I've posted in the wrong section. Can a mod please move?
