the 1996/2000 van is one of the top 5 aerodynamic vans out there, if not the best, but you knew that all ready
maybe a clutch thats used with a 4 popper 1.3L could possibly fit a 1.0L?
thinking out side the box....
ive heard of the sidekick 1.6L 16V engine being adapted to a FWD geo, there about 100/110 hp. just need to find a FWD manual from one of the cars they made that will fit it
my sidekick is 3,000lbs+ gets about 27/29 on E10 and its not very aro shaped.
it also has the added drag of RWD and part time 4WD
