Anyone seen this in a Yellow Jacket Coil Pack?

Yet another misfire,

R33 Gtst unmolested

intermittent, yet continuous when occurring. Subsides after a minute or so

Drives perfectly 90% of the time

New Plugs, new fuel filter

Did attempt to wrap the packs to no avail.

Cash is tight at the moment, trying to avoid replacing these again.

Thoughts and opinions would be appreciated.

Thank you

If you can't find any info on yellow jacket coil-packs dying on these forums, I'm sorry to say you obviously haven't searched hard enough

Mate you'd be surprised... The canadian stagea owners swear by YJ's and the shit Autobahn88 sell...

 

You can lead a horse to water...

 

Aaand, i never did get my refund or replacements for my 6 coils melting.

The search function on the forums is pretty awful. I think the guys here have just seen a few threads in their time from browsing, but these don't always show up in search reliably.

First thing's first: suss out which one is playing up. Mine used to do it when idling, so I was able to pull the wiring loom from each one until the idle didn't get even lumpier, then I'd know which one was problematic. Then I tested that coilpacks in a different cylinder to rule out the wiring loom as an issue - the problem followed the coilpack.

Once you've done that, check out the coil spring - it may be too short or not seating properly. Either buy a second hand OEM one to replace it in the meantime or contact Paul from Performance Wise - he was pretty good when I had coilpack issues and sent me one for free when I sent him back the faulty one. I ended up with another issue down the track though and I'd had them for 5 years so I figured it was time to update - went to splitfires and they haven't missed a beat I have to be honest. The YJs were good as a bargain for a few years, but long term not so sure. Time will tell if the splitfires are much better.

    • GCG is a good company, they're a major distributor for Garrett in Japan as well.
    • Nah, OEM washer bottle and brake fluid reservoirs are fine I don't know what it is with the plastic that Mazda used, some plastics, like the washer bottle and brake fluid res are fine, and still look new after 20 years use, where as the coolant expansion tank, and PS reservoir, that I replaced with new OEM items when I first got the car, turned yellow and started getting brittle a few years later If the dirty yellow stained plastics didn't trigger me there wouldn't be an issue, but they did, much like the battery bracket....... Meh As for going back to work full time to support car stuff, nope, why, because I own a Mazda NC MX5, not a Nissan R series Skyline 🤣
    • I've never heard of CJ-motor, so can't advise you on them. I'd just go straight to GCG for a GCG highflow though. Seems no point to use a middleman. I'm somewhat surprised that the price on the CJ site is lower than the GCG retail price. Even though CJ would get a discount of some sort, you would hardly expect them to give up so much margin. Maybe the price is out of date? Having said that "I'd go to GCG"...when I did my highflow, I went to Hypergear. I did this https://hypergearturbos.com/product/rb25dethighflow/#tab-dyno-results with the R34 OP6 450HP profile. With the BB centre (extra $400) and intially with the standard boost actuator, but I eventually got him to send me the high pressure one when I got to the point of being able to actually use it. Ends up costing the same sort of money as the GCG highflow, but this is, of course, the turbo that I KNOW has a shorter length core and so moves the comp cover rearwards. The GCG apparently doesn't do that. My mechanic also swears by the GCG highflow, given that we have another turbo rebuilder who does something essentialy the same as theirs, using Garrett wheels. He says it stands up at really low revs and makes good power. I haven't pushed my HG highflow past ~240-250rwkW yet (should have a little more in it, but unclear how much) and it does have a fairly gentle boost ramp. OK, it's much better now that I have gotten my boost controller tuned up on it.  A lot of my earlier unhappiness was because I couldn't keep the wastegate flap as closed as it needed to be (including some mechanical issues). I'd still prefer it to boost up nearly as quickly as the stocker, and it certainly a bit slower than that. So maybe the GCG one is worth the first look (for you).
    • Ok thanks 🙂 I will higly consider this. Any "known" company for a good reviews and experience to send that off? Is that CJ-motor good one? Or go straight to GCG site? I need to use VPN to even find some of those "shops" let alone access them 🙂 
    • You can literally put in as much WMI as it takes to quench the combustion totally (and then back it off a little, obviously), and it will keep making more and more power. The power comes from the cooling effect of the water (and the meth) and the extra fuel (the meth, which also has massive octane). It is effectively exactly like running E85. One might be slightly better than the other, but they are damn close. But with either you can lean on the boost or the timing (or both) waaaay more than with just petrol and the results are similar. Here's the first thing I googled for an anecdotal bit of evidence. Can't access the attachment without being a gold member, but it is there for the getting if able to, or searched up elsewise perhaps. https://www.hpacademy.com/forum/general-tuning-discussion/show/wmi-vs-e85/
