I have a 97.5 and i have a internal coil i was wondering if you can buy a different distributor to make it external or if modifying the old one is all you can do? i want to get msd for my car but i want to know what im up against
Its easy, I have done it on Hondas all the time. You just need to interrupt the two wires that go to the internal coil and send them to the MSD then from the MSD back to the internal coil. I usually drill a notch in the cap to run the wires through and repeat the notch every time I bought a new cap.
If you want to ditch the internal coil and use an external coil, its more of a challenge, but it is easiest with a MSD power tower and single coil wire. Just determine where the cap connects the output of the coil to the center pin. Drill the power tower to contact that point and wire the MSD like normal. It is usually a good idea to remove the internal coil while you are at it.
Lastly, I think I remember that the Nissan ECU does not like the crank signal being bothered by the MSD system so you will probably need a Tach Adapter to prevent an Check Engine light. Do a search for the part number.
