i think there was a couple knocking about circa 1990-91, i never heard that sue did 16 ish though but definately one, the parts were not complete and various parts needed specialist manufacturers help to produce what was required.
i even remember the original owner of the g reg collins escort 4x4 rs turbo's name its john bridget or bridget the midget.
its all in my memory bank, now whats the crack about onions,thats the second time someones mentioned onions to this evening.
there was another cosworth tuner back in the good old days when i was starting out learning my onions and it was called Greenlight, it was in London and the bloke who ran it was called Gerrade Sauer, he was well into motorsport stuff and wrote for iirc car and car conversions as well as being a cosworth tuner,he did a rs1600i in met blue for a customer who was rallying it,that car came from another ford specialist who could not complete the car due to not all the transmision parts being available, the car had a lot of the bits that sue collins had. in them days there was a ford specialist who managed to get hold of stuff ford was developing and secrertly using but wasn't availablr through main dealers parts departments.
one other example was one of the first 16v zeta engines that later became known as zetec got banned from ford racing (vecta fast fords don't ya know) due to the engine not being available from ford to buy yet the scrap yard had them in for sale.
it was in a escort rs turbo and the head iirc was on the cvh block back in oooh 1991 before the mk5's got 16v's.
ford got bummed by lancia for using a name they owned the copyright for so the engine then go called zetec,course to me its a zeta still init
