Is there any more to gain from the 2g conversion compared to using upgraded coils like accel MSD CC and so on?

rxtory

i also would liek to knwo the answer to this question. I in the middle of making the 2nd gen one but thats because all the parts were available at my school to do so with.

Kentetsu

I started out with the 2nd gen conversion, and it worked great. Then I added the "transistor trick" and the results were simply unbelievable. You can do the 2nd gen conversion with the TT for about $50.00 which would probably be cheaper than upgrading your coils and will certainly give better results...

iceblue

I have all the parts. I just don’t feel like fooling with it. I would rather keep the stock look with coils.

It sounds very good and all but has anyone actually tested both? I am sure I could just go compare the output of each coil and figure it out if no one knows.

rxtory

yea the only thing i got to do now is get the 2nd gen coil then my "TT" will be done

Kentetsu

Iceblue; Trust me, there is no comparing the stock ignition setup with the TT setup. The difference is night and day. Stronger idle, better gas mileage, much better power at the top end and everywhere else.

This mod made more of a performance increase than my Racing Beat exhaust, modded carb, and E-fan all combined. Seriously...

iceblue

well I am sure but I am not comparing hte stock ignition. I am asking about 48output coils like MSD blasters vs the TT.

no_name

****! I better do this if it gives that much power!

iceblue, go search, this is not comparable to a simple coil upgrade, (difference is like comparing addition of a Holley to supercharging) Go read the original thread, the comparisons have been done, the tests have been done, many happy users and you are still questioning the upgrade, believe your fellow 7 owners or dont do it. Simple really.

iceblue

That was a wonderfull post of an ***.

Hmm coils are no longer comparable to coils it seems.

Arockrx7

no he is saying the TT will produce a strong spark faster than the stock at high rpm. when you just get a msd coil the spark is just hotter.

Some people just dont want to hear.........figure it out yourself. Glad I could help.

iceblue

That's what the amplifier box is for :-P

Ice, you didn't play well when you first came to the 2nd gen forum, please try to do better here.

You have recieved good and proper advice. If you think the MSD will work better for, then by all means, spend the extra money for a comparable upgrade. Some people do feel better spending more, we in the 1st gen section, however, are a bunch of creative tightasses.

After reading all this and searching up, I'm wanting to do this (and I almost was wanting to do MSD). My only major question: how long would it take to do the transistor trick? When I first read the thread on TT, it blew my mind into a spin.

Are these units still available?

Thanks, Ed

Contact gsl-se addict - its about 45 for an assembled unit. And 35 for kit. Happy shopping

Kentetsu

Installation is a cinch too. The only tough part is figuring out where you want to mount the coil pack, but there are plenty of choices available for that.

Iceblue- Read up on the TT. You asked for advice, and I offered it. If you want to drop money on a mediocre upgrade then suit yourself. No skin off my nose either way... Welcome to the 1st gen family, now behave or we'll send you to your room!

There are a couple options. Just depends how comfortable you are with electronics. I will have a kits available. This is on a labeled professionally built circuit board. All you need is to drop the parts into place and solder. It is kind of like solder by numbers. I am also doing assembled units if you don't want to mess with it. I would estimate the kit version would take about 1 hour or so to put together at a beginner's pace.

iceblue: There are many options for upgrades for the 1st gen ignition. What is best for you depends on what parts you already have and what you think will work best for your application and budget. trochoid is correct. There are not many aftermarket parts for our cars and the few available are often too expensive. Because of this, we have to develop our own mods with what we have available.

Don't expect much difference if you just replace the coils. Newer, higher voltage, coils will give more consistant firing over more conditions. However, if the stock coils aren't misfiring, there isn't much to be gained.

The various direct fire options are good (DLIDFIS, 2GCDFIS, TT, MSDDIS). These are a "wasted spark" or late leading spark setup. Basically there is less loss since the spark doesn't need to go through the dizzy cap. The additional spark 180* later also helps burn up leftover fuel. These options are generally inexpensive. The MSDDIS is the most expensive out of the buch (MSD box, MSD DIS coil). Hyper4mance2k has this setup. He really likes it a lot.

If you go with an MSD box, the MSDDIS is probably the best option. If you fire through the cap you lose the late leading spark and have extra loss through the cap. You can fire other types of coils with the MSD as well. One thing to consider is that the MSD boxes are quite large. Many people do not like the amount of space they require in the engine bay.

For me, I think like this:

-Low budget: DLIDFIS or regular 2GCDFIS. These are a nice upgrade and very inexpensive. They may not cost you anything if you already have the parts laying around.

-Mid budget: TT Better gains than DLIDFIS or regular 2GCDFIS, but at a little extra cost. The big advantage is that you are using the superior 2nd gen ignitor. It handles more current and can keep firing strong at high RPM. The TT was developed to take advantage of an ECU fired coil (2nd gen pack) without the cost and wirng of adding an ECU.

-Higher budget: MSD with DIS coil I am not sure if there is an advantage over the TT or not. You do get multiple sparks over certain RPM with this setup. Some will argue that a single long duration spark is better than the multiple short MSD sparks for our long combustion chambers.

-Going all out: 2nd gen CAS or similar with igniton ECU (Megasquirt, Haltech, and so on). Best control over spark timing. These setups can fire most ECU fired coils (like the 2nd gen coil/ignitor). Some of these don't fully support trailing spark. You will have to check on that.

So that's a basic rundown of your options. You will just have to decide what works best for you. Hope this helps.

That mainly what I was looking for. Just someone who has dynod and or both setups to comment. I was also weighing the stock look factor. My car is cherry and I want to preserve it for an antique with only simple and effective mods.

I am so busy with my FC project and miata project then work onto, I just did not want to spend the time making the mod myself.

As you said selling them complete if you would make me a TT kit I have the coils I will gladly pay you.

Sure thing. Either a kit or assembled is fine with me. We are working on some sort of noise issue currently. Once this is sorted out, I will ship the new circuits. I understand about wanting to keep things stock looking. If you make a bracket, you could mount the 2nd gen coil without changing anything major. The TT is setup to be able to switch to stock easy. I have mine setup to where I can switch back to stock in under 5 minutes. Makes it nice incase of coil/circuit failure. Always good to have a backup.

GSL-SE Addict how much for an assembled unit?
I want to use this on my turbo project.
Thanks, Ed

kbeefy

Last I heard was around $45 +shipping from france, there was some mention of shipping to US and shipping from there. I'm sure someone will correct me soon.

iceblue

awsome just let me know how much to pay you and how in PM, I will send you some money.

DeRFmAn

yeah me too. I wanna start doing mods to my stock 12a.
