Word to the wise. Becareful about the MSD DIS-2 system. I actually had that installed on my 90 1.6 miata. I had horrible problems with the box kickin the two-step rev. limiter in at about 3800 rpm. Between me and the tech guy we couldn't figure it out...the two-step feature wasn't even hooked up. I will admit they are good people to deal with, very friendly.
