I've all but given up on looking at engine and gearbox combos ,I'm looking at going very light weight with a 24 speed shimarno set up chain driven to the sierra back diff. This is after watching Bugsy malone again. :D
Yes I know this will be silly on the A13 but think of the congestion charge!

well you could weld a sprocket ring to the crown wheel and then run a chain up inside where the prop would go fit all your gearing in there if you want to go 24 speed (shimano is good i hear)
im just not sure where you would fit the brake peddel and would you be going for one crank or two?:rolleyes:

How about a Nissan engine? The old scimitars with the 135bhp engine used to shift, with a 200sx engine, gearbox etc a roadster would be great!
