they make some type of adapter for the SCI to work with the eclipse. you have to purchase a separate distributor for it to work. doesnt seem worth it and doesnt make much sense. i was just looking for opinions. i am gonna check out the crane components though. thanks for the advice. do you think one of these is worth the coin though? i know we lose spark at higher rpm's but im using zex plugs right now and work much better than the NGK's that i had. just opinions always help.
