I'd be interested to see a micra engine taken to full potential- they don't have much as standard, but then neither does the A12. I have seen a turbo micra that pulled 100FWkW, but nothing in N/A format.

sorry about the hijak.

I like the A15, but my biggest love/hate is the torque- mine is all down low, not much up top, which doesn't work well with the gear ratio's- if you change at 6500-7000 you are well past the torque peak in the next gear, so it makes for a dissappointing drive. IMO you want to cam them up so the torque peak is at around 5500.

EDIT:
oh yeah- no direct experience whatsoever in putting carbs on a modern engine, but if you want a real frankenstien, there are castings available for DCOE onto suzuki swift GTI's- as well as stroker kits (or possibly a block swap I cant remember offhand), and they also bolt up to the vitara 5 speed box.
