ignition upgrades?

[4g63tc]

does anybody make an ignition upgrade for our dis systems?

I've been looking and i can't find one anywhere.

The best ignition out there is stock trust me. You will not see a noticeable improvement with an MSD or similar unit.

really? i just wanted to know for sure thanks!

MSD DIS-2

Hyper: I have an MSD DIS 2 and it doesn’t make a worthwhile difference in spark.

 

[4g63tc]

but they're saying the firing duration is longer than stock ensuring better combustion? wouldn't you need more spark/power under high boost / high fuel situations?

 

[4g63tc]

besides isn't it almost 800 bux for the dis 2, and the adapter? i just wanna know everything before i drop that kind of change.

What they say being the operative word. If you want to spend 500+ bucks on an ignition upgrade you don’t need be my guest. I am trying to give you some of my experience as a “wiseman”. What I have seen over the last few years of drag racing DSMs seeing what works and what doesn’t. There are several people in the 10s on the stock ignition FYI. Make your own decision let us know how it turns out.

hey im asking for advice, no need to flame.
I just want to be able to make an educated decision based on the pro's and con's of upgrading or not. i respect your position as a "wiseman" however i just want to know the simple facts. does it or doesn't it work and if there's no real benefit why did you buy one?

i'm all for saving money, it's hard enough to come by!

Thank you

It doesn’t or it doesn’t make a $500 plus difference in spark. If I was doing research into a particular product I would find a car that was making the type of power that I want to make and look at their setup. Maybe I would take a look at a few cars at that level or maybe a bit higher and see what they are using to get a feel of what works and what doesn’t. If you do that you would see that there is a lot of people in the 10s and 11s with no ignition upgrades. That shows me that the people that this product should help most reject it. What does that tell you?

Well you just might be able to infer that I bought it and realized what little good it does and want to protect my fellow DSMers from making the same poor decision. But in this particular case it was on the car when I bought it ad I got through just as many spark plugs and have the same ignition issues that people with stock ignition have. Its not just me either.

ok thanks that's what i wanted to hear, because i semi wanted the dis to help with the fouling plugs problem i'm having like every 4-5 thousand miles. and i am using ngk but the oem plugs since i'm not boosting over 15psi.

again thanks the money can go to suspension. any suggestions on sway bars?

Spark plugs are pretty cheap. You would hate to see how often you have to change them on a car making close to 400hp on pump gas. Are you sure that it doesn’t have something to do with your tuning?

I don’t have a 2g but I don’t think you would want to replace the swaybars if your suspension was other wise stock. The addition of shocks and springs made a HUGE difference in my car and there are much nicer/better solutions for 2g cars. I would take a look at the suspension forum for answers to your questions.

 

[4g63tc]

well i have the coil overs/ struts worked out already i just would like to go a larger sway bar at the same time while i have the suspension torn apart.

as for spark plugs i was going through a period of running rich due to a bad mas sensor plug, and bad o2 sensors i replaced them all but i think the damage was already done to the plugs.

I have a Crane Cams Hi 6 ignition system. I thought that was the answer when I actually just needed new stock coils. I can not tell any real difference with the Crane ignition. Spend the money somewhere else.

Get 2 lead coils from an 86-92 RX-7. Turbo or non, they are the same.

Fantastic suggestion I will be setting these up shortly with my Haltech. Thank you for the tip.
