Julian,
If you want to get maximum bang for buck then a suck thru is obviously the
way to go, find yourself a turbo manifold and make an adapter up to fit the
carb onto the turbo air inlet, make some tubing up to go from the outlet to
a stock inlet manifold, throttle cable, exhaust, tune it up, and away you go
Good luck finding a right wheel drive gearbox for your E15- all the aussie
ones were all wwd as far as i know
- Tom
PS I think Paddy has a EFI manifold for an A series motor, might be worth
asking the question
