I can't add anything other than this. When Roadster S3 production was suspended, as MMC were looking to Ford as another replacement engine, I was "interested", and happened to bump into Steve Morris at the factory. Obviously a 3.7 with six speed box was super tempting, although in the end I decided to stick with my S1. The thing was, that Ford were "not interested" other than supplying a (plug in) crated engine, box and instrument set, and there was no deal available on price, which MMC would have liked to negotiate down a bit.
So what Ford supplied in the end would have been a standard set.If BBK is right, then MMC could have changed the throttle body, but being price sensitive, I'm not sure that they would throw another £500 into the mix. So yes, it's a mystery.
