I have a 97 Cobra and am looking to upgrade ignition. Mods on car are 2.1L KB s/c running 6-7 psi boost, Kooks headers and x pipe, Magnaflow exhaust, Acufab Oval TB, 90mm MAF, 42# injectors, JLT CAI, MSD coil packs and wires, and other stuff. I am looking at MSD DIS-4 plus. I have used MSD 6AL in the past but never on mod motor. Does anyone have this ignition or a set up similar, Please chime in?
