While the insight's powertrain would be impressive in the aerocivic, the layout would require extensive (read: expensive) modification to the aerocivic, whereas the VX engine is essentially a bolt-in application, only needing some mild extra wiring and a mount swap to be installed perfectly.

I'm not sure what the Insight's engine layout code is, or how exactly the mouting system is designed, but I do know that it requires expensive engine management controls, and I've yet to see anyone actually get one to work perfectly in another chassis.

I have, however, seen an Insight chassis used to make 9 second passes on D-series engines... (read: Bisimoto Engineering)

Also, noted in MetroMPG's budget EV thread, the Li-Ion battery options are prohibitively expensive for the average enthusiast's budget.
