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...

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.

      RB25DET with solid lifters - which cams ?

      They are under bucket shims. Tomei provides a test shim kit and then any measurement of shim required.

      I always wondered how you were supposed to buy a set of 24 buckets and somehow magically have every single one of them yield exactly the desired clearance. I would have thought you'd need to assemble a cam with either 12 "sample" or "example" buckets of known top thickness (or a single such sample/example 12 times over!!) measure clearances at every valve, and then do the usual math to work out what the actual "shimness" of each bucket needed to be, before buying the required buckets to make up he thicknesses that you didn't have on hand.

      I now seem to be limited in power due to my rev limit/hydraulic lifters in my built RB25. I'm looking into converting over to Tomei solid lifters. Question for anyone that has done the conversion. I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  I don't know where I got this idea, as so far I see no mention of this in any of the Tomei documentation. It just states I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!? There's no way it's that simple, I must be missing something?

      Why am I hitting a power wall with my stroked RB25?

      I couldn't agree more. I should have started from the get-go with a NEO or solid bucket conversion. I started looking into converting over to solid lifters yesterday. Now for some reason I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  But I see no mention of this on any of the Tomei documentation. It just states that I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!?
