Factory Coil Pack Fix!!

[meet07]

After my turbo upgrade I realized that the 25 was breaking up really bad at anything over 10psi. Since Ive been told several times that its probably my coil packs I decided to try something before upgrading to the lsx packs.

1st off I took a little trip over the Home Depot and picked up some GB(Gardner Bender) Liquid Tape and got some 3M electrical tape from work.



1) I removed all the loose oem paint so that the tape had something to stick too. I was gonna throw some scocth brite on them but decided to take the short cut.



2) I went ahead and painted everything up. I made sure to hit all the gaps as well:



3) After about 2 layers of LT I let them air dry. The GB tape has a odor so it might be best to let them air dry in a vented area. I had the back and front doors open..


4) While the coil packs where drying I decided to tape up the boots. I must say that now the boot fits back onto the coil pack nice a snug. I actually heard a little pop when pushed all the way back onto the packs...lol

After a about a hour of drying the coil packs where able to be handled. This is the finished product:

I would also probably clean the spring with some brake cleaner and then add a little Dielectric grease to it. I have not yet been able to drive the car but I will on tuesday. we will see if this fixes the problem.

Im running some NGK copper bcpr7es's and there already pregapped to 0.8 I may upgrade the ground and rewire the power wire to the coils with a relay. Not sure yet but we wil see

any feedback would be greatly appreciated..

i've seen this done before and my only concern would be that the rb coils already run very hot and this is basically just insulating them and holding more heat in. other then that good job man.

Nice a good cheap fix.

But if your still having problems, def go with the LS coils!!!
They're awesome!!
When my car was running PIG RICH they still fired off great.

The LS1 coils are a better shape, so they are easier to mount.

Check out my LS2 Truck Coil Thread, when your ready to do it

Looks good! The other thing you should do though is pull that spring out by twisting/pulling and clean the brass or aluminium bucket it sits in. I just hit it with a dremel real quick. It was all corroded and stuff. That's all I did to mine and not only did they stop miss firing at 1.6 bar, but I upped the boost to 1.9 bar for a little while and had no problems with it.

**I just noticed you left the ends not covered (like kinda yellow/clear looking sections). Cover EVERYTHING and I'd put a few more coats on it. Make it thick. If it were me, I would cover the plug connector and stick something in the hole in the boot where the spark plug goes, then dip that thing in your insulator of choice. Repeat several times. Nice and thick.

for some reason I was thinking maybe that gell looking stuff was kinda like a breather for the hardware inside?? I think ill go ahead and drill into the boot side of the coil. It was clean looking after inspecting it but Ill go ahead and do it to be on the safe side. And pull on the spring to re create tension...

[meet07]

Update!! Coating the coil packs 3 times didnt do a think for me. Maybe there not getting there proper voltage at higher rpms due to a weak alternator or the fal slim fans?? I dont have a clue. I might just go ahead and order some truck coils. Then I wont have to ever look at the ignition system again = /

You will never regret going to LS coil packs. They rock!

[Cjmartz2k]

That sucks. I've been able to bring back about 75% of the bad coil packs I've run into. O well. Do you think it's more than 1 BTW? Have you tried narrowing it down? I'm not trying to steer you away from LS1 coils, but it's not terribly hard to narrow it down to 1 or 2 coil packs then just replace those. Much more cost effective.

Should have grabbed that set from me when you had the chance

[meet07]

When you was here I had already had a back up pair that I had been collecting from the local junk yard for like 2 years. I ended up selling them to the gentleman that did my manifold/dp work... But yeah I really would like to save them If i could but I might be getting some truck ls-whatever coils for like $130.00 bucks and some spark plug wires for anouther 30 bucks or so....

But it sucks b/c i want more boost!!

[Cjmartz2k]

Wow, $160 for the whole set up? Sounds like a pretty good deal to me!

There really coming down in price. To bad your all the way on the other side of the globe...lol

j/k Im sure you have connections..lol

[meet07]

Nistune has a boost cut function called Load Limit on there program that I just remembered. So I decided to open up the bin i've been playing with to check out the value. 128 all the way across. The max value is 255 which you can set it to if you pretty much want to eliminate it...So I maxed out the value and ill be testing this on Saturday. Im hoping this will fix the breaking up issue. Either way I already have some truck coils on the way. Muaahhhaaa!!

[R32ONP]

so has anyone tested this method??? me thinking that coating the coil will make it overheat more???

[Cjmartz2k]

You are thinknig about it wrong. The heat itself doesn't make them miss. The heat cracks the plastic and the cracks/weak plastic allow the spark to arc to places it shouldn't be going i.e. the valve covers. And yes I have tested it. I have never ran anything but stock coils on mine at 1.8 bar of boost and a bit north of 500rwhp.

I just coated my SuperSpark coilpacks with 2 coats of liquid tape. I was having terrible misses over 16psi. We've tried a lot of other things and I believe it's down to the coilpacks not holding up. Once the engine is completely back together I'll let you know if it solved my problem. Thanks for posting this... Hoping for the best.

[meet07]

I want to say that I was mistaking the coil packs starting to fail for the injectors maxing out. Anything over 10psi she would break up. I have no dyno proof but there is a guy on youtube with a similar setup. At 12.5psi he was putting down 370 something to the wheels. so that would make sense to be putting down something around 330-350 to the wheels at 10psi....

[Cjmartz2k]

Yeah, kinda interested to see if it works for ya. Maybe we should start a poll Seriously though, I'd say it works probably 50%-60% of the time (WAG). Also, like I said, the factory coils are good for much more than I threw at them, which was 600hp and 1.8'ish bar. I know people running more than that on them. The ignition system works as a whole, not one part BTW. The spark with always get "hung up" at the weakest link. Bad plugs? Miss. Fix that? Now your coil packs leak. s***. Fix those, ignitor goes out. I slowly rotated through stuff like that breaking until I found good pieces. I'm sure new factory stuff would have fixed my problem right away, but I'm cheap and there's a lot of stuff in JY's around here

[radianation]

I have Series 2 coilpacks with built in igniters. Thought I would mention that incase the overheating is going to be an issue?

[yotik]

excellent thread. I'm having a similar problem and suspect the coil packs since it runs rich a times. Going to
try this method and see what happens. Any solutions meet07?

[evildave32]

I just repinned some coils out of a 97 maxima for my 20

[legit240sx]

just got done,
engine has some boost leaks in which im only at 2psi at the moment but
I did notice less break up on the high end.
alittle rougher idle but could be unrelated.....
