I wonder if anybody can help, I seem to remember somebody was supplying a big bore throttle body for a M20 2.5 engine on an exchange basis. Are they still around? Or any other suggestions?

This is on a tuned racing engine but the rules of the championship state that we run standard injection so rather than fit a larger throttle body from a different model with all the problems of linkage etc, we had heard of someone who bores them out and supplies them ready to fit.
