| Post subject: | Replacement Coil Recommendation |
Before I bought the car, my 63 Valiant was converted to mopar electronic ignition. Currently, the coil being used is a Mopar Performance one (chrome cannister). I see what appears to be replacements at Summit Racing and Ebay for about 45.95. I want to replace the current coil with another but I am finding it hard to justify the expense. Can any of you suggest another coil good enough for a street car? Thank you. |

Follow the reco for the MSD Blaster coil in the see HEI upgrade instructions. |

Dan: I read your article and instructions. Based on what I read, I purchased an MSD Blaster Coil PN 8202 to replace the Mopar Performance Coil. A couple of items in the instructions bother me: 1. "This blaster Coil Kit is intended to be used with an MSD Ignition. If installing on a stock, points style ignition system, a 0.8 ohn ballast resistor or resistor wiring MUST be installed." I am installing it in an electronic ignition system NOT points. The present ballast resistor is a 1.2 ohm. 2. "It is recommended to mount the PN 8202 .... in an upright position." My present coil is laying on a fender. I would prefer to mount the new one in the same manner. Can I? Thanks for your help. John |

Hi John, I've used the Accel chrome coil, but while it seems to works OK, the cases corroded very quickly on the 2 I have. I have a MSD canister-type Blaster coil in my Ford; it works fine. None of those 3 seem to work noticably any better than a new stock-type coil, as far as I could tell from just driving. Either your stock ballast or an aftermarket ought to work fine with the new coil. One fellow I helped out ran his stock coil w/o ballast for a year, until, as he put it, the coil "blew up". Keep in mind that some ballasts (the Mopar point-type) are designed to get hot and increase resistance (0.5-2.5ohm) to save the points at low RPM, but improve high RPM operation, while others (the Mopar electronic-type) keep it constant (~1ohm) to ballast failure. Red hot wire-wound resistors tend to corrode and break easily compared to much cooler ones. You'll never probably be able to notice any difference between a 0.8 and 1.2ohm ballast. In general, less resistance=more spark, but more heat and more load on your electrical connections. The factory wiring will very likely give problems if the overall resistance on coil primary + ballast is significantly decreased. These canister coils ought to work in any orientation, but I've noticed that the ones used in a nose-up attitude never seem to develop the leaks the sideways mounted or nose-down ones sometimes do after some years. I don't worry about it and just put in like the factory did. Good Luck, Kevin |

Why do you want to replace the Mopar Performance coil? |
