sue collins built one for a customer who ended up working there and was built from bits that were gen ford, they turned up in breakers yard along with 16v zeta ( thats the proper name for a 16v mk5 escort engine) and other stuff.
the car was brand fire new and nearly ended up on a q but the owner who was a bit of a fart put pressure on the vro and got it greg'ed.
i saw the car, it wasn't any differant looking exept a set of Revolutions ( Rs Baz's favourite wheel

, sorry Baz

) in white and the fun stuff underneath.
there was a 4wd rs1600 i but thats another story
