Increase the spark

[Nismoking]

I'm coming up with a simple ignition upgrade, and I owuld like input on the missing Items.

subject- NA ka24de s13

Wires- Aurora (spelling)Direct fire coil ???Plugs???

ANysuggesitons on what items I oshuld use for ???

Also I'm looking for a coil with a hotter spark than oem and bolt-on.

BTW I did a search, but everyone is trying to do full ignition system upgrades, I mearly wanna replace things.

Thanks for any adviceChris

NGK wiresNGK plugsNissan capNissan rotor

That's basic, and will be fine for most N/A setups..

There are people using MSD coils.

[Nismoking]

Ok I'm fine with the NGK plugs- will v groove be okayCap and Rotor, will stay oemBut can use the Aurora wires instead of the NGk's?

Also what msd coil do people use, I didn't think msd would make a bolt-on coil with a hotter spark?

Thanks,Chris

you'll have to modify the wiring for any aftermarket coil a little bit, nothing majro. I run nolgoy wires and a coil, nissan OE cap/rotor. and NGK iridium plugs, more than adequate even under boosted applications. Nissan ignition systems are quite stout and dont relaly start causing problems until larger build ups(not the case with most other mfrs)-chet

Bosch Platinum +4 Spark Plugs, trust me, I just put them in my car, much smoother idle and acceleration.

You have got to be kidding.

All the other reviews that I've read about Bosch plugs in our engines resulted in HORRIBLE performance.

As for me, it's all NGK for plugs and wires, with Nissan cap and rotor.

THe spark can only arc from the electrode to one end, so having four doesnt really DO anything, except provide different ends to arc to....

I dislike bosh ever since I tried them on my two 300zx's and they ran WORSE than with my old NGK plugs. NGK all the way baby!-chet

[SunshineAcid]

nah, i put the plat 4's in and it runs better than ever. smoother idle, smoother revs, you can even hear the diff.

I run nolgoy wires and a coil-chet

So you replaced the external coil? Would you mind sharing what you used? I'm figuring out different ignition upgrade routes at the moment Thanks Chet!

[Exar-Kun]

nology coil info here:http://www.nology.com/profire.html

thats the one I use, I didnt use MSD because I had heard from more than a few people that they didnt see power increases from it...:/

O well, the nology wires and coil worked great for me, better mileage and a notable stronger pull.-chet

Thanks for the info man

i'm wondering what both of you guy's previous plugs looked like. bosch platinum +4s are complete garbage. if your previous plugs needed to be replaced, anything would feel like an improvement.

Omit typing errors its late haha

I have bosch plat 4's as well they run good. I think some people dont torque their plugs hahaha. But mine run really well I get great pull im talking awesome I never ran the car b4 relaly wiht my old plugs but damn with these new ones its way faster than my dads 200+ hp mustang. Or feels like it at lower rps range. But honestly the difference isnt going to be much I think it jsut helps to premote a cleaner and even burn in the chamber.

I just read this off of the Carlos Muhbahoy website about Torque master spark plugs. They look kinda cool. heres the website o for the plugs

http://www.torquemaster.com/

The sit eis kinda gay looks lik it was done on geocities but damn they have a dark photo with the spark going on the plug and sheesh it looks so clean and evenly sparked. It looks much better than an erratic spark from a single arm or 4 arm plug.

Heres a pic of that spark flash. Looks kinda doctored but I think they were trying to get the spark visible probably to bright for camera so they had to tone it down.

hey chet, what is the model on your coil? can you point me to a text for the rewire of the ditrib

[chandler]

a spark of only 7-12 kilo volts is needed to spark the cylinder, unless you are running extremely high boost, or high compression or lean burning, you dont have a need for a "hotter" spark, the platnium 4 spark plugs are a design from back in the old days for airplanes, they were mandated to have more than one electrode incase one fell off. chandler and all this is from my drivability class

[Jookmasta]

so then is it worth goin to the msd blaster coil 2? its only 30 bux but will it make a difference? o ya, ill also be runnin a msd 6btm on my ka-t

[Scott McLellan]

Exar-Kun, where did you get your Nology wires. Does that capacitive discharge thing help? What's the cheepest place for them? I'd probly get rid of the plugs that came in my car (Splitfire "V" shaped electrode) and run iridiums of some sort. What brand and where to get good iridium plugs? Thanks!-Scott

[Exar-Kun]

Denso and NGK make nice iridum plugs, the DENSO ones are a bit "better" but also heinously expensive. the NGV iridium IX's cost 6-10 dollars each, and work wonderfully, the Desnos cost almost 15 dollars, but feature an even finer wire electrode and a small "u" groove in the plug gap to enahnce spark burning.....but I doubt that's worth it to any with under 300hp.

I got my NOLOGY plug wires from (yeah, I know..)NOPI, back before I closed my wholesale account with them. I dont know who has them the cheapest, and yeah I ran the wires with old plugs, new plugs, then with new plugs and the coil.

THe wires felt pretty good, revved much smoother. From what jeff and ed were saying, MSD setups wont net me any HP increase on the dyno over those wires until I'm over 14psi of boost, and dennis kalman(340hp KA24DET) actually lost 9hp with his MSD setup...

as far as the plugs, Jeff and Ed(http://www.balancedperformance.com and http://www.dynotuner.net)really like iridiums, and ed swears by them, much like good synthetic oils....quote Ed: "its just worth it to know they wont cause a problem, and could help you gain a little extra power.."

Just my 2 cents, I used Iridiums on my modified Buick GN and they were horrible!! I lost a ton of HP and the plugs fouled within a few weeks. I went back to using standard ACs and the car picked right back up. I havnt tried them on my 240 for this reason, I'm using NGK V-power right now.

[Scott McLellan]

You do know you have to gap the plugs right? No, I think all the parts store guys I've talked to always say they run AC's on their 85 el camino or whatever. I think maybe older cars might be effected differently by plugs because of maybe a weaker ig. system or combustion chamber or something cause I've seen several tests where more modern fuel inj. engines respond real nice to iridiums. It still doesn't really make sense though that your buick didn't like them though... What kind of "fouling" are we talking here?

[cory2081]

Well, my Grand National was highly modified (forged pistons, aftermarket heads, cam, TE-61 turbo, etc) Under high boost (20+PSI) the Iridiums just fell off in power. After a couple of months, the car started running badly. I removed the plugs and went back to ACs...the car ran beautifully. I just couldn't get the car to run good with Iridiums. It just didn't feel good to me at all. FYI: Buick GNs have a coil pack (DIS) The ignition system is FAR from weak, it can shoot a spark up to 3 feet, I've seen it!!

Yeah, I know all about plug gapping. High compression or boosted applications usually use .035-.040 Gap B/C of higher cylinder pressure. Another FYI: Iridiums are PRE GAPPED, Gapping them can damage the electrode.
