ignition- tell me whats best...

[96chevysfa]

well, i will be buying a ignition system in a week or two, and i havent decided what to get. my main goal out of this upgrade is fuel economy and to scure my rough idle, but the performance is a plus as always. so wha to get? and where to order from? i want a module thats somewhat water resistant, because it will get wet, and something with a rev limiter. money really isnt a factor, as long as its reasonable. so tell me whats best.

I have a 96 5.7 in a scsb truck. I did a little reasearch on ignitions for my truck some time ago. what i found is that your stock ignition system is more than capable. Most of what i found on the Jacobs type stuff was negative. throw on a quality cap and rotor, a quality set of plugs, the stock are platnum i think, and work well. add to those a set of taylor wires and she will purr like a kitten.

thats my .02 ,,

I would agree. Installing an aftermarket ignition to cure a rough idle is a bandaid on a shot gun wound. Get it running right first. Contrary to what most advertising says, almost nothing will give you better gas milage. The OEM stuff is pretty damned good at that. What you see in those ads is them taking a truck like yours that is running poorly, bolting on a bunch of stuff that makes it runs correctly, then measuring the difference. Same results most times could have been had with GM parts.


Then, when you're ready, the MSD products are always the best you can buy. ;)

the reason it has a rough but steady idle is cus i need to replace the plugs and wires, thats it.

I ran with a Jacobs Ultra team (control unit and coil) for a while. But it burnt itself out...not completely sure why. :cussing:

I replaced it with an MSD 6BTM and an MSD Blaster coil. I've had no problems with their stuff at all...

I realize that, but if you can't keep up with the basics, then you don't need an aftermarket ignition. That won't solve your problem.

i do keep up with basics, but what im saying is, if im replacing my wires, and plugs, and maybe a few other things, why not buy a package. the idle isnt that bad, its just to the point where it needs new plugs, the last time i cleaned the plugs was over a yr ago.

For sure go with the Taylor wires. The spiro pro wire set rocks!!! I have ohm tested a lot of wires and theirs are the best around. I agree that the aftermarket ignition box won't do much for you. Esp. not in MPG. The Taylor wires, correct plugs, new Accel cap with brass contacts, new rotor and you will be set. Now that being said I personally run all of the above and a crane HI-6 box. The crane box helped from part throttle to WOT on hills and under strong loads. Dyno testing showed about 3hp and I have no MPG increase to show. The OEM system is pretty good, the GM ESC (electronic spark control) already provides spark over 20 degrees of crank rotation which is the main sales pitch the ignition boxes. Also take your ignition module down to Napa or local parts store and have them test it. That controls spark dwell and if it is bad all of the above is worthless. Later-:D
