i had a MSD 6a with blaster 2 coil installed on my turbo ABA. it did drive much better/smother. the hardest part was to take apart the stock coil. but after that it was quick.
the car does seem to idle smoother but I can't really make a valid comparision since I installed a new dist. rotor along w/ the coil. The real reason I chose this coil is because it was about 60-70 bucks cheaper than the oem unit and who knows... maybe the hotter spark will help out.
Definitely gave it more spark because my car idled higher and the inside of my coil wire where it connected to MSD had all types of bright green/blue corrosion starting. Definitely noticed a major difference in idle when I took the MSD out. Car was a lot quieter and idle was smoother.
i believe the hotter spark and the MSD system created a smoother running car. i switched back and forth between the stock coil and the MSD. while the stock coil did work, the MSD made the car run smoother and didn't break up at higher boost levels. the MSD blaster 2 coil is a lot cheaper than the stock coil also. no more cracked coil housings.
I burned out 2 jacobs coils using the Bosch ICM with CIS before I put in a MSD blaster that held up fine. The Jacobs would get burning hot to the touch, I returned them to autozone.
anyway, my friend put one in his Toyota truck and it smoothed out his idle and boosted midrange
I put an msd blaster coil #8220 in my fox and it works fine... No ping and I also get better fuel mileage due to a hotter spark for a clean burn.
I went with the MDS Blaster High Vibration coil http://www.msdignition.com/coil_blaster_3_8222.htm in my rally car because of the inherent suceptibility of an oil filled coil to extreme shock. The MSD is epoxy potted and fits in the stock location. It does use the American style connector for the high voltage wire but I also use Magnecor wires which will accomodate both. In the process I also improved the supply (+) wiring and ignition control (-) wires. In the end my oscilliscope showed me a much cleaner and longer pulse was being produced which probably helps combustion under otherwise marginal conditions.
I have a 1776 and was running the pertronix with the bosch blue. Rebuilt the top half of the motor and now have a MSD coil (because it was the only one I could get on the weekend), and I have noticed no changes in engine performance.
Bought new coil. Lucky to get good German Beru unit for little over $90...last of luck. Put in new coil, still no spark.
