I'm interested in upgrading my ignition system, without spending money needlessly. I looked at the MSD 6a Ignition system and for the price it looks good. Has anyone installed this system? Is it a pain or easy to do? And does it connect to the current coil or does it somehow replace the coil with a direct connection to the distributor? Any comments please. Thanks, Ed

he's running a turbo, it will help out plenty. I went with a 6a myself with the gm harness....took about 5 minutes to install, real nice stuff

There are a lot of mixed feelings about the 6AL.

Fire451 and I both ran MSD systesm with tweaked 2.8 V6's and I ran 15.00 he ran 14.99 on pump gas no nitrous and no turbo.

It is an all or nothing deal.

6AL box
SuperConductor wires
Blaster II coil
MSD Harness Adapter.
Delco Steel Core Plugs. No fancy plugs, STEEL CORE OEM. Then replace them at every other or every 3rd oil change.

I got better gas milage
Better high rpm power
Better low rpm torque
Better overall drivability.

Be cautious.

The MSD 6200A can go faulty and you can't test it. Mine showed up as a miss in the low rpms, that I could not locate. It got worse, it started bucking after it warmed up, and under 2500 rpm. It was real embarrassing.

MSD fans, including speed shop guys, and mechanics told me my miss could not possibly be the MSD... HAH!

After spending alot of cash on parts I didn't need, I unplugged it and the problem disappeared.

Bottom line, Pyrthian is right. The coil is good enough. I'd be looking at good wires and plugs with a high output coil. But if you don't care how much you end up spending, why not put on the MSD?

didnt know he was boosting - then yes - get the box.
I got a 6A also & the MSD coil, with the GM harness - super easy install. also, with the GM harness, its easy enough to bypass the box. with my car - the box makes NO difference at all. have driven with & without it. I now drive without it.

The 6A made a great difference on my last stock 2.8. I put in a Crane coil which did very little. Then I installed the 6A which made the engine rev so much smoother from 3500 on. I now have it on my 3.4. It is worth the price to me. I suspect that those who did not feel results did not increase their spark plug gap as the stronger ignition suggests.

MSD 6BTM will give you the enhanced spark as well as easily adjustable retard. I used a MSD/Vortech BTM (retard only) along with a MSD Digital 6 Plus. I used this setup on my turbo lt1 as well as the turbo fieros with good success.
