Yep, a supermini before its time.

1049cc and 85 Bhp...although I had mineon a rolling road shootout at the time and it did 99 Bhp, more than a few Ford RS Turbo's did in reality at the same event, much to their embarassment

Apologise for the missprint, my objective in writing the article was to highlight the low/high compression piston avaliablity/qualities. My car is fitted with the low compression, I intend to fit the high compressionones over the Winter, out of curiousitywhat type of Weber have you fitted ? thecar with thetwin choke performed disappointingly on the day.

Hi All

Correct me if I am wrong but I always thought UK & rest of world cars had HC pistons and 147BHP and the US got LC and 125BHP?

I think the issue is that the HC pistons have been unavailable for some time, so many rebuilds have been done with flat tops.
