Upgrading Ignition

[Zeusimo]

I Have A 78' 620

I've Read This A Couple Times

And Thinking Of HEI

 

This Is What I Have

 

MSD Blaster 2

 

Stock Dizzy?

 

Do I Do Anything To This Of Do I Leave It Alone?

 

Or Do Basically I Just Need To Get A HEI And Wire It Up Like This With MSD Coil?:unsure:

If all you're looking to do is upgrade the coil, then you should just be able to replace the stock coil with it. If you're looking for some other kind of upgrade, you could replace that remote ignitor box with an HEI unit, or replace the whole thing with a matchbox coil. But if all you want is the coil, it should wire up like the stock one. I believe that thread you linked to is more for people with L-series that have points, you should be fine to keep the remote triggered dizzy.

 

Somebody correct me if I'm wrong.

you dont have to do the HEI swap since you alreay have EI. teh only real reason to do an module would be if you didn't already have EI.

[banzai510(hainz)]

looks like you have EI already. Leave it alone

[Zeusimo]

so i could run the MSD coil without a ballast resistor?

It was my understanding that if you have a stock ignition system that you have to use a ballast resistor. At least, this is what MSD told me

[Zeusimo]

I Think That's Meant For Points, Apparently I Have EI

And Isn't That The Same As Using Stock Coil? :huh:

[banzai510(hainz)]

Yes you can run that MSD coil inplace of your stock EI coil. I assume its for the BLING factor as I think the Japanese coils are good already.(maybe if not better).The hp upgrade will be in ones mind more than at the rear wheel on this one

 

I would watch these companies now. even Accell has outsourced its super stock series coils to CHINA

 

the MSD Blaster 2 is I believe a .7 ohm coil and for points would need to add a ballast to close close to 1.6 ohms on a stock datsun sytem.PLUS using the already stock ballast with it for a total of about 3.2 ohms
