will this work and is it a big difference,has anyone done this...
I have a gslse and I got a set of coils off a 2nd gen

 

it can but you must either convert your leading coils to gsl-se addict's "Transistor Trick" ignition conversion kit and use the second gen leading coil OR MSD to leading coil. Currently there is no way to use the trailing coils UNLESS you convert you're whole wiring harness/fuel system to 2nd gen or use aftermarket engine management system. In any case, it makes a big difference.

 

Yeah, leave the stock trailing and get a 2nd Gen leading coil. You *can* run it without the "Transistor Trick" box, but it doesn't work nearly as well. Remember though, once you change from capacitive discharge to direct fire, you'll have to change spark plugs in the leading. Some of the second gen guys have had good luck with NGK BR8EIX, even though they're not specifically made for our cars (they're Iridium plugs made for a certain kind of motorbike IIRC). Other than that, just use stock 2nd gen leading plugs.

It's possible. Not sure exactly what else is needed from the 2nd gen to make it happen thou. The car I recently bought is an 88 with a 12A. Having troubles keeping it running thou. It dies out after a minute. Apparenlty it ran fine in the past, just need to find the problem.

 

an 88 with a 12a??? wat? ive never heard of a 2nd gen guy swapping a 12a motor in. unless u mistyped something.... ha. its fi right?

 

Nope you heard right. I believe the last owner cooked the engine and had to settle for a 12A due to not being able to find any good 13Bs at the time for a reasonable price. It's got the 12A carb, choke and fuel pump.

 

Do you run into any spacing issues when you switch to the 2nd gen plugs? And did the overheating issues of the "Transister Trick" box get sorted out?

 

So far I've had better results using the 1st gen Nippon Denso plugs than the 2nd gen plugs. However once I get it to stay running for longer than a minute it may be a different story.

 

Using the 2nd gen coil without the TT is still an upgrade over stock. This is what I am currently running until we get the heating issues with the TT sorted out. Use the leading coil pack, but leave all of the ignitor wiring intact (just unbolt the wires from the terminals on the coil). Take the + and - wires from the stock leading coil and move them over to the new coil. Install the plug wires directly from the coil pack to the spark plugs. Works great. You can do this with the stock spark plugs, but the plugs from the 2nd gen will work a little better with this system. Try it, you'll like it!

 

So just by moving the + and - wires form the stock coil to the 2nd gen coil it will work?

 

Well, you have to move the spark plug leads over too, but yeah.....

 

thats cool. I just got a 2nd gen leading coil so Ill be doing the 2GDLIDFIS either tonight or tomorrow morning. Hopefully I notce a difference.

 

What Is The Transistor Trick?????????IS THAT SOMETHING I TAKE OUT OF THE PARTS 2ND GEN THAT I HAVE

 

No, the transistor trick is a system designed by GSL-SE Addict (very large thread always floating around on the top two pages or so of this forum). This basically translates the signal between the 1st gen ignitor and the 2nd gen ignitor. Being able to utilize the 2nd gen ignitor makes for a tremendous improvement in ignition performance. Unfortunately, there are still a couple of bugs to be worked out, but I believe that he is just about ready to release the new and improved version. Until then, just use the 2nd gen coil without the ignitor. If you just disconnect the wiring between the 2nd gen coil/ignitor, then when you upgrade to the TT unit then you will be able to use what you already have. Just don't cut any wires on it when you do the install.

 

I also did the 2GCDFIS upgrade best $10 I ever spent, 5 mpg improvement, better smoother running and easy to install, just search under 2GCDFIS.....

 

Thanks!

 

DO YOU HAVE PICS OF IT IN YOUR RIDE

 

I just did it yesterday and it does seem to run smoother. Did you use different plug wires when you did it? It seems like my stock wires wont stay all the way plugged into the 2nd gen coil.

 

We are still working on the TT. There was a delay getting the 2nd gen coil from France to here and I didn't have time to test. I just rebuilt my engine, so my car has been down. My 7 will be picked up in a couple days to ship from Oregon to Virginia. It will take 2 weeks to get there. I can test at that time. I sent my 2nd gen coil to Paul in Australia since he needed one and I wouldn't be able to drive my 7 for awhile. I am going to be picking up another coil pack and trying some different ballast resistor once I get to VA.

 

See if you can push the covers further up the wire, they need a longer reach on the new coils. If that doesn't work, then you can either order 2nd gen plug wires or pick up a set of "build it yourself" wires from any parts store. I built my own, because the 2nd gen wires are very long. The ones I made are about 6" long, just enough to reach from the coil to the plug.

 

Hey Kentetsu, is this your set up?:



I've had this piture for a while and have always wondered what wires those were.

 

That is Angel's old car (DJAngelicon on the forum, used to be known as TheLatinHeat). I'm not sure what wire they are, but you could send him a pm. I could also ask him for you.

DO the FC coils use a different end on the plug wire than the FB distributor cap? Because my wires dont seem like they are on good, and even bordering on falling off.

Edit: Didnt realize I just posted this a little bit up the page.

 

lol, did you read my response a little bit up the page too? Try to push the covers up further on the wire so that the end will extend down into the coil all the way.

 

Just for everyones info, I have setup a small site with the information on the TransistorTrick modification. http://rx7.pw.cx/transistor_trick/index.htm

Note that there are heating issues as Kent pointed out, we are working to resolve these Kentetsu had a good suggestion on the first page of just using the coil part of the 2nd gen coilpack and wiring into the stock setup. I would go for that until the TT has matured to the next level (although I continue to run the TT :P)
