I think I might try this when I do my 2GDFLIS, the price really is right.

P.S. What if I used the 2nd Gen ignitor in the bottom of the coil?

i mounted my gm igniters rite off my disty by the original top screw, i think they are slightly more reliable ythan stock, and yes i carry 2 spares, ps they put out 20%more spark duration than the stockers , my tach worked fine after i wired around the factory harness sraight to the tach, and off the leadings instead

Dankus,

Any pics of you setup? I'd like to see for myself how it looks when you got it all done 'cause I'm thinking about switching to the HEI modules myself.

Since you put them right in the stock location you probably didn't need a heatsink right?

Can you explain, maybe in more detail, how you got around the tach problems when switching to the GM units? Did you just rewire the tach or something?

Thanks!

Here's what the HEI module looks like:



W - Connects to the positive lead at the distributor.
G - Connects to the negative lead at the distributor.
C - Connects to the negative side of the coil.
B - Connects to the positive side of the coil.


Does anyone know which mag pickup connector on the distributor is positive and which is negative? Knowing that bit of info and by following jeff20b's DLIDFIS wiring diagram it should be a snap to construct. Thoughts anyone?

Has anyone done this and is there a wiring diagram/\?

This shows which color wire, from the pickup (red and green), goes where on the ignitors.

For quick easy future reference!

Thanks Much. The price is a bonus along with my general theme of simple is better. Won't feel bad throwing my box in the trash.

I've had the HEI on my Probe GT for over a year and 20k miles now (due to a "dead" disty) and haven't had problems. Seems like a good/cheap alternative for the RX7 too. I'll have to give it a shot later.

As for finding the module at stores. It was used on '75-82? Gm vehicles.

The GM part # is 10482820
Niehoff part # DR400
Wells part # DR100 (what I have)

I started poking around and found out I have a couple more wires comin put the dist. I need to figure out where they go. But I wanted to tell you I bought the gm ignitors. I stopped a the local pepboys and they only had one. Figure that out. A part that is known to fail that was in a couple a million cars and they have one. Well none now. And boy did he look at me silly when I changed it from a 79 nova to a monte carlo.LOL

I carry a couple of J109s in the glove compartment of each car, just in case. And they were cheaper used than the GM ignitor.

The trick is to make sure the heat generated by the ignitor is dissipated satisfactorily, which is why you must use heat conducting grease to mount them. You can get it at the autostore checkout counter, or at Radio Shack.

25 years of RX-7s and 4 on the road now, and I've never lost an ignitor.

Keep a spare J109, a packet of heat sink grease and a little offset (right angle) phillips screwdriver in the glove box and you're covered.

Using GM Igniters-cimg0507.jpg Cleaned the wiring up today somewhat and thought I would send a pic for the thread. Can everyone else tell what's going on in this? Sometime when your real close to it you assume it's as plain as day.
Now if I could get it to start warmmmmm................. timing ???24 and 16??
If I do this the bolt is almost at the end of the slot. Do I need to bump the distrib over a tooth?

Hi, we need an igniter, have put in a rebuilt engine, and need a source for parts. This is our first RX 7, 1980, bought it running but leaking oil like a sieve, got the engine rebuilt, now seem to have to replace most of everything else. Put a new starter in, now the igniter has gone. Do you know where we can get one? Thanks, we are new here,
