My MSD 8247 LS2 Muti-Spark Blaster Coils Project
""Since most of us don't have the time to read the whole thread, I created a word document with just my inputs in hopes to make it easier to understand.""
After reading Jeff’s (mazdamaniac) posts in the Corvette LS1 Ignition Coil Project https://www.rx8club.com/series-i-aftermarket-performance-modifications-23/corvette-ls1-ignition-coil-project-137423/ I decided to pursue the same concept but instead of using GM LS2 coils I went with MSDs 8247.

Take a look at this website for more information regarding the LS1 and LS2 coils.

I purchased four MSDs 8247 LS2 Multi-Spark Blaster Coils on eBay for $245 including shipping.
So far, I plugged one MSD coil to the leading (L1) side by individually connecting each wire to the four MSD coil pins.
The car started right away and with an inductive timing light I checked the spark output. I revved the engine up to 8k rpm several times while checking the timing light for spark output and to make sure that the spark duration/ratio was constant (sorry but I don’t have an oscilloscope). Everything looked OK.
BTW Jeff is has logged hundreds of miles thus far on his RX8 with the LS2 coils with no issues whatsoever.

I'm waiting for four D581 plug connectors to arrive so I can fabricate plugs for MSDs and splice into the OEM coil wires. Once installed I’ll take the car for a spin and will update the thread with pictures. I hope to have everything installed by the end of the week pending arrival of the D581 plug connectors.

Got an email this morning to notify me that the D581 connectors are on their way and should arrive no later than Saturday, I hope. The price for the four D581 connectors was $26.68 including shipping.
Also, I went to Home Depot yesterday and purchased a few pieces of hardware to fabricate the bracket for the MSD coils. Total expense $7.58

Looks good Juan, but curious............why not the Mazsport ignition?
I think it would still fit where you are located now because of the SC????? I'm not sure though.

Just to clarify that my OEM coils are not located on top of the engine since I’m running a Pettit Racing Super Charger. My OEM coils are located just behind the radiator where the bottom of the OEM air box used to be. See pixs.

Update, connectors arrived in the mail today. I assembled the connectors with 16 (eight inch long) pair of wires and later plugged them to the coils. Everything is now ready for swapping the coils tomorrow afternoon and hopefully have them tested on the car tomorrow evening. Will update tomorrow night along with pictures. Stay tuned.

Well people I gave it my best shot.
I think I should get an E for Effort and a big fat S for Success.

I don't have a video camera, just a digital camera that can take 30 seconds non-audio clips. The first clip shows starting engine, revving and back to idle. The second clip shows me holding an inductive timing light while my son revved the engine. Enjoy.

I will take the car for a drive tomorrow and provide more feedback. Right now where I live is raining like hell and under a tornado watch. Therefore, no need to take any chances on the road. Tomorrow is going to be a beautiful cool air Florida day.
