SR coil packs

[TRBOMOFO]

Alright i wanted to ask some basic question i could not find from searching

#1 When 1 goes out do they all go out

#2 If goes out will it mess anything else up (wires, ignitor pack, plugs, other coil packs)

#3 How can i upgrade from factory craps

i had one overnighted from cali then another one crapped out so i got 2 more and i am running low on money

college is gay

Sounds like an electrical issue. Better check the ground wire, and unwrap the wire loom going to the coilpacks, see if theirs any cut wires, or loose.

They are not run in series, so if one fails it will not disable the others.

I would be very surprised if a failing coilpack had any negative effects on any other ignition components.

There is no upgrade. It's very uncommon for one to fail at all, let alone two back to back. That makes me suspect something that isn't the coilpacks themselves is starting to go bad. I'm not sure it would have any effect, but have you tried replacing your ignitor? it also wouldn't hurt to go over any grounds that you can get at on the motor and make sure their contacting surfaces are nice and clean.

edit ^^ duffman beat me to it

i c i c

i have checked the harness and all is good

so thats why im so confused

Wrong, there is an upgrade, you just dont hear about it often, because the standard direct ignition setup is rather robust.

There are two options, the first being Splitfire's complete coil pack ignition system. http://enjukuracing.com/split-...4_381

The second is a slightly more home brew remedy. I have seen people use remote mounted coils from a Corvette. Try searching for it, I know there is info out there.

[Neil]

Ah yes. Splitfire. I knew I was forgetting something, but my trusty subconscious was telling me it wasn't worth googling. Not exactly known as a brand name that represents a high level of quality.

For all realistic intents and purposes I stand by my original statement. i'll have to check out the 'vette thing though, just to see what that's about

It is a very viable option, one of the biggest killers of coil packs is heat, and the GM style are remote mount. That, and AFAIK, the vette guys are making prodigious power numbers, on stock coils. Ive seen it done on both KAs and SRs.

Quote »remote mount[/quote]ah-Ha. Interesting.

http://phase2motorsports.store....htmlI run a 8 gauge ground to each of my coil pack's. Better than $85 For this.

ah i have seen a bunch of this stuff

i wonder before it was said that most of the time they dont just go out unless its something electrical

what if

the coil pack valve cover o ring leaked oil into the whole chamber and i drove it around unknowning ???????

i had to vacume oil out of the chambers a few times tilll i got that sealed right long story

[duffman1278]

You'd see oil inside where the spark plugs sit, in that hole if they were leaking. If that happened, I don't understand why you didn't change the seals. New ones shouldn't seep oil, I've had oil go through those seals before and it wasn't THAT much oil that got through. I'm going to stick with electrical issue. lol

na i had changed them finally after i found out that oil was in there

I'm sorry, but why did you do that? Nissan's engineering of the direct ignition system's coilpack sub harness is not able to be improved upon by adding thicker ground wires to the pre-existing ones. The grounds on each c.pack can't be more than 14awg, so while it must have also been really physically tricky to do, the 8awg will never have the potential to carry any more current than the stock wires do. Each coil's ground runs to a common that bolts to the intake manifold with a ring terminal, so as long as that's clean then that's as good as it gets since the manifold is in turn grounded to the battery with 0awg. Small wires are used where low current is seen. If the wires were too small for their intended purpose they would literally fry.

Wait, did you try to emulate the Circuit Sports design (lol shiny gimmicks) by crimping on ring terminals and slipping them under the c.pack fastening hardware? Because that thing actually does even less than tapping the actual grounds would, because the only function of those bolts is to keep the coil packs from vibrating out of the plug wells. The tiny metal sleeves pressed into the coilpacks themselves that the bolts thread through are not part of the circuit, all they do is prevent you from crushing the surrounding plastic when you snug them down. I'll bet you $500 you wouldn't see even see 5 miliamps of current running through that circuit sports thing.

when i first did my swap i was having spark issues. turned out to be ignitor chip was going out. in figuring this out i moved coils to different plugs to verify coils were bad. but spark was intermittent. even bought new CAS. luckily a mechanic friend had a q45 chip i got for $20 and boom, spark was fixed. the one thing i picked up about the chips is the backside is metal and it bolts to its bracket. i was told to put that gel stuff between the two. the chips can overheat and short out. good luck

Yes you are right, I did! I was bored. It couldn't hurt right? It seem's to start easyer.
