if you undestand what it takes for a coil to fire i say it can be done. just a matter of feeding power to each coil and running the correct coil pairs on the negative side for triggering. i thaught of doing it but my funds are low right now. plus it would take a bit of fabricating on the valve covers. would the bennefit be worth it? i say just get some real good plug wires and call it a day.
