Hi

Talk to Dave Colledge at Retro Ford

Not only has he done Zetec on 45's but has also done Zetec on Jenvey Throttle Bodies and also ST170 Focus motor on Motorbike Throttle Bodies.

You could also speak to Troy at Northampton Motorsport as they have mapped these engines for Dave, but also have a customer of their own running TB's on Weber Alpha management in a Focus.
