I've been following all of the recent posts on converting to toyota coil-on-plug ignition systems and I'd like to find out if it would be worth upgrading my 91'. Right now its a mainly stock (nonturbo) 140k daily driver and my coil and wires are both old. I am hoping the added power of the new coils should net me at least 1-2mpg? I found a set of coils with pigtails for about $60 and the group buy on the dwell reducer should make the end price somewhere under $150 - but is it worth while for a naturally aspirated car or should I save money for making real power later on.

 

Itīs always worth it. Donīt matter of FI or N/A. Youīll sort out a weak point in the construction of your car.
