Buying MSD Ignition & coils????

I spoke with a tech specialist over at 4WD Hardware, he said all I would need is just the "box" and the coils. Is there anything else that I need? I am running a stock distributor with morosso 8mm wires w/platinum plugs. What do you guys recommend to get the most out of this ignition system without having to spend the $300 on a new distributor etc..?? I am running a 258 4.2.

Re: Buying MSD Ignition & coils????

Looks like you almost got it all. I would get a high performance distributer cap, and see if it will keep crossfireing to a minimium. If crossfires still ocur, some technitions will tell you to drill a small hole in the cap. This is not a good idea in a Jeep, b/c of the moisture inherit in offroading. I would suggest a new distributer if it continues to happen. Your wires should be able to handle the power, as well as the plugs. I have the MSD 6A and Blaster 2 coil on my 258 and it makes a big difference. Idle is much smoother, throttle responce better, and mpg improved by 3. I used Accell 8.8 wires, Blue Streak distributer cap, and Split fire plugs. By the way, when shopping for plugs, don't put too much faith in those large, split and multiple electrodes. Look for a plug that has a large fixed electrode(I hope this is clear), and you will get a better spark. This is why I chose the old style splitfire, but Champion truck plugs are good as well.

I'm sure that Team Rush could enlighten us all more about what to use(and explain it better). Just telling my experiences.

I bought the MSD6a through Summit for around $135.00 plus shipping. I needed a connector or two and about $12 ea. This is for a 1980 258. I got the Ford TFI coil per TRs suggestion. I agree wholeheartedly with Jason regarding performance and mileage improvement!! John

I don't know if I can do any better job than you did, YJason!
You have grasp of what's going on.

I'll tell you who can give you a better advice than the guy at a 4X4 place is the tech crew at MSD.
They are REAL sharp guys.
Tech line is 915-855-7123.

There is no need to change your distributor.
The pickup coil in your distributor is exactly the same type that MSD uses in all of their expensive billet distributors, and unless you plan to try and run NASCAR with that 6 cylinder, the distributor you have is just fine.

All you need is the MSD 6 series module.
If you go to the wider cap, like in the 'TeamRush' ignition upgrade, you will reduce crossfires, multiple fires to more than one terminal, and firing to ground that results in dead misses.
Using the taller rotor with that cap keeps the spark energy from finding it's way to ground inside the distributor.
If you need instructions on this upgrade, which uses all off the shelf parts for ford trucks, let me know and I'll re post it.

Going to the E-core (TFI Style) ignition coil will give you stock ignition some real fire power.
(Do the cap and rotor upgrade so the spark energy created by the coil can get where it's supposed to go, when it's supposed to get there.)

The MSD module will work equally well with your stock ignition coil or most of the aftermarket coils.
The MSD module doesn't care what coil is hooked up to it, with the exception of a few 'Mega-Super' coils.

Buy the MSD adaptors to wire to the stock connectors so you can still go back to the stock ignition in a pinch, or if you sell the vehicle.

Let me know if there is something you don't understand.

Later folks, Aaron.
