I'd be very interested too. I've been considering shipping a kit from Trinidad. If I could get a frame, shafts, alternator mount and a servo relocation bracket over here I'd pay over £500.00. Ideally I'd want it to be an install with no body mods at all, using the full injection system and I think the Micra setup at the moment is the closest to that. I might still go Suzuki Swift though, the power from the Swift GTi is good and the oil filter is just in the wrong place on the Micra engine!
They often fit a remote filter on a k-series swap so theres no reason it couldnt be done on a CG13
