Ok, it's been a while since I have been on here, sold my car a while back to pay for one of my kids college. So I building another car. Like my last car I'm swapping to a navi motor. The last time I stayed with the original coil packs; however, this time I want to go COP. Looking for input on how to do it. I have the navi engine harness and the car is a 96. Car I use the navi harness? I so what PCM? Car will get boost down the road, so I'm not sure about the adapter harness. I had the Red Monster harness on my old cobra (before the navi swap) and it was great, but heard that isn't good for boosted motors.thanks for any inputs.
