Electronic Ignition Swap?
Is there any benifits in changing the Ignition set up from a 12A to a newer one, like the Distributor Cap? I found a post like this and maybe it is what I was trying to explain in an earlier post about the 6 point ignition.

You mean there is a way we dont have to deal with the points / distributer ? please please elaborate on this direct fire mod.. illustrations would be nice too.

Well, I believe that if you currently have points, then you would have to start off by picking up a later model distributor. As long as the dizzy had the ignitors on it, you'll be all set. Check out the link https://www.rx7club.com/showthread.p...hreadid=243350

You can usually pick up the needed parts (2nd gen coil) for 20 bucks or less from either a junkyard or Ebay. Installation takes maybe 20 minutes or so. Instructions can be a little confusing, so I was thinking about drawing up a wiring diagram to make it easier. I still have photos of how the wires get connected, so maybe I could post those if nothing else. In my opinion, this is the first mod that should be done due to the low cost and ease of installation. Smoother idle, small change in gas mileage, small performance boost.

I'll see if I can post some pics when I get home tonight. If you put the pics together with the information in the FAQ it should be pretty simple to accomplish. I should point out too, that if you combine this with the "transistor trick" (about 30 bucks more) then the installation is greatly simplified and the horsepower gains are greater. However, Kent will be leaving for France shortly so supplies of the kits are short (so if you're going to do it, get ahold of him ASAP).

Just to clarify, all 7's come with electronic ignition except for the '79 models. Converting to electronic ignition is a good idea. You get rid of the points and have a system that is more reliable. To convert, you can just grab a distributor (with the ignitors on it), the wiring, and the coils off an '81-'85 car. Everything will pretty much drop into place. You can take it further by doing what Kentetsu is saying. By replacing the leading coil with one from a second gen, the spark happens every 180* (extra spark per rotor) and the spark doesn't need to travel through the distributor cap. This means the spark stays hotter and the wear on the dizzy cap/rotor is reduced.
You can take it a bit further with the "transistor trick". It is in this thread:
https://www.rx7club.com/1st-generation-specific-1979-1985-18/transistor-trick-2gcdfis-411312/
You don't have to worry about the details of what it does, but basically it allows us to use the 2nd gen coil and ignitor with our ignition system. The 2nd gen ignitor is larger, can handle more current, and keeps an intense spark all the way to and well beyond the redline. I think this is the best option and I am not just saying that. The performace gain has been noticable by me as well as others over the stock setup and even the regular 2nd gen coil mod. I should have a couple spare circuits leftover, however, when they are gone, they are gone. I will be out of the country as Kentetsu said, so I won't be able to make more until I get back.
Hope this clears things up a bit. If you have any questions, feel free to ask.

Hey gsl-se addict, Thanks for the info and I would be interested in doing this as well. Right now my engine looks like this.
What are the things that needs to be remove when doing this? I know I most follow the thread you gave but, just wondering what parts I need to get from you and what parts I need to get from the junk yard from a 2nd Gen.
Angel,

Hey Angel. I sent you a pm, but I'll post here too so that others will know. All that you need from the JY is the leading coil pack from a second gen (can be NA or T2). Then just need to add the circuit and make a couple connections. It is real easy. The 2nd gen coil can be mounted on the inner side of the strut tower. This is much easier if you don't have A/C or PS in the way. The leading coil won't have to go through the distributor cap, so you will remove the leading high tension wires. You can then move the trailing over to the leading position on the cap (T-->L, T1-->L1, T2-->L2). This takes advantage of the carbon button inside the center of the cap. This means one less gap the trailing spark has to jump.
Any other questions, feel free to ask.
