With the MSD box, all I would have to do is to run the corrolating wires straight to the coils: correct. Pos - Neg
Would I remove the old coil wires since they run to the distributor or would I run them all together? |
Originally posted by 813KR$ I have heard 1 msd 6a box could run a whole row of coils with no problem? I read it on one of the DLIDFIS tutorials. |

I am looking into air bleeds and have realized that my 600 doesnt have adjustable air bleeds. Iam wanting to find out if and how to tap my air bleeds, because I think I need to richen my top end?
I think it is on Paul Yaws web site, about the msd box being able to push many coils at once, he said he talked to the msd tech people? They said something like "Hell yea it would push a row of coils"? |
Ah, Well your carb is a 4160 model right? I'd suggest you get a metering block kit for the secondaries so you can change the fuel jets to do your richening/tuning. Dont start fuckin with the bleeds just yet. Your sec "jets" may be the key to your problem. And they arent replaceable on a standard 4160.
Yea, well I dont believe everything I read. And unfortunately I ran out of tires last time out on a track day, and that was one thing we were experimenting with. Only had time to go from MSD in direct fire leading mode to stock. I plan to test all possible setups, but that takes time and a good plan for a test day. Along with good rubber LOL. |
My last question I promise.
I was reading the directions on the mazspeed web site and I just wanted to be sure. I connect the green and purple wire from the MSD box straight to the leading ignitor and replace it back into the distributor. |
No, you dont use the igniter with the MSD. It works better by being triggered off the mag in the dizzy.
Quote: THIS IS VERY IMPORTANT!! Hook the GREEN wire on the MSD to the RED wire on the distributor and Hook the PURPLE wire on the MSD to the GREEN wire on the distributor. |
So remove the ignitor all together

i jsut put my MSD and blaster coil on yesterday. read this article. it's how i did it and it works great

Originally posted by Rx7carl V8kilr can you tell me why you wouldnt use one MSD leading and one Trailing? Putting an msd box on the secondaries is counter productive, the spark occures more towards the top then the bottom of the rotor, this gives a slight force in the reverse direction the rotor is currently spinning, but because most of air and fuel are towards the bottom of the rotor face the primary spark has more pushing force then the secondary, the secondary spark is only there to help complete the burn of the primary spark obviously for multiple reasons, I'm sure it helps out a bit with emmisions as well. Disconnect your secondary coil and go dyno, wont notice much difference. Originally posted by Rx7carl And isint splitting splitting one MSD output to 2 coils effectively halving the spark energy between the 2? Originally posted by Rx7carl I understand that one box can fire 2 coils, but can it deliver enough spark to keep the power up at hi RPM's? Ran my car well past redline, just ask jeremy from here how fast and far my redline went. I dont think I could get it to stop on redline if I wanted to. The needle would jump so fast once it hit 6k I couldnt stop it before 7k, it would usally hit about 8k before I would shift. |

OH YEAH
!!!!!!!! DO NOT MOUNT YOUR MSD COILS IN THE STOCK LOCATIONS OR SIDEWAYS AT ALL !!!!!!!!!!!!! I got pics if you want to see what happens when you do |
Let me see some pics, I have always mounted my blasters side ways with out any problems? What happens?
Rx7carl: I already have my metering block. Iam currently running, no choke, 62's in the primaries and 65's in the secs. With a 1'' spacer under the carb. |
Does any one know, if it is possible to hook up the stock tach to the MSD box? If so, how? What wire goes to the MSD box?
|
there is a small plug hole in the side of the MSD box you plug it into
|

what do you guys think about the jacobs rotary pack and coils?
|
Racingtang: I know where the wire for the tach goes onto the box, but what wire is supposed to be connected for the stock tach?
Purple82: I have also had my Blasters sideways for years and my brother? wassup with that? |
Originally posted by purple82 I've had them sideways for a couple of years. MSD suggests not mounting this way but they don't forbid it. What happened to you? Looks like they have been burned and they no longer put out a good spark, the stock coils fire better. My car runs like shit with the bad msd coils now so I put the stockers back in and it runs fine, until I get some blaster SS coils. |

So if I run a wire from the MSD box to the neg side of my trailing coil, should the tach work alright? Doesnt sound good to me? I currently have the neg on the trailing coil hooked up and have no tach? Dont know why, because the tach worked fine before the direct fire install?

I'm sorry but I am new to alot of this rotary stuff. I did not pick up alot of the pictures for some reason or another. The dizzy is the distributor correct. I will wire the MSD box directly to the distributor wires, correct. The black boxes in the distributor are the mag pick ups correct. I just don't want to screw this up.

Check out the Paul Yaw site it explains everything.
