I know G10 Suzuki Swift turbo engine(3 pot) will do 130-150 with turbo. They are good engine and I have a spare engine which is ready make it into turbo spec. If you are interested, let me know.
I have Vitara pistons for this engine to make it 75mm bore!
I have to say I've been keeping an eye on this engine too. I regularly get to drive my mother's C1 which is a 3 cylinder 1 litre and I've always been impressed by that so I really must try out one of these Fords sometime. Looks a good possibility for a Midas I'm pondering a more up-to-date engine for mine but first I need to get the car on the road.
