i was hoping that someone can give me some feedback as what is good brand for replacement coil packs- i have ocational hesitation on take off and i have swapped them with second hand OEM ones, but really i'm pretty sure i will buy new ones shortly as this is really common on all skylines!

Apart from SPITFIRE is there any other brands that are more reasonably priced?

I mean when i look at my application i think that spitfire may to over kill for my purpose. I will look into it and make a decision shortly.

The best feedback is from user rather than saleman/ company, so i value this greatly. Thank you

^^ I have Splitfires and they are great!

I have seen Yellow Jackets for about $370 + and Splitfires are about $480 +

Ppl seem to think Yellow Jackets are good, if you don't want to spend as much on Splitfire, Yellow Jacks seem to be a good option.

When I was looking at coils I was tossing up between the three major brands. Splitfires, Yellow Jackets and the Just Jap coils all had much the same mix of reviews. I.e. great product, sporadic cases of people receiving faulty items but in all cases were replaced by the manufacturer. I reckon you'll be happy with whichever one you go for.

What's important to me is after sales support. I know Yellow Jackets back their product because after I posted an honest review of them on the forums (including report of a minor installation issue I had with one of the brackets on a coil) one of the Yellow Jackets guys came on SAU and queried me about it, offering to replace etc.

got yellow jackets for myself. fixed my misfiring i had for 2 years. i tried heaps of things including swapping 2nd hand coils, taping them up with high temp tape, 0.8mm gap plugs, rewiring my ignition power supply with high current relays and changing cas. i now run 1.1mm gap iridiums no probs. although i do remember having to file the bracket or something coz the yellow jackets were slightly bigger.

sorry to bring up such an old thread but can someone confirm this?

are yellow jackets a straight fit? ie , nothing required to replace them?

They are a straight fit, no modification required. Just make sure, if you have an R33 GTS-T, that you identify whether you are series 1 or series 2 - coilpacks differ between these two models.

lol

Most of them are probably made in the same Chinese factory and will work fine, but I have used YJs in 260-350rwkw cars with no issue. Even done back to back with Splitfires - the differences were negligible and some areas of the dyno graph were in the favour of YJs.

Plus Paul (Performance Wise) is a great guy, if you ever have issues he looks after you.

as matt said, the brand probably means zero

any brand new coil pack will perform better than 15+ yrd old coilpacks

oem, splitfire, yellow jacket

i put splitfires in my ecr33 when it had misfire on boost, fixed it no problems

I got a set of YJs from Performance Wise and about two weeks in two of them died. I contacted Paul (from performance wise) sent him some pics of them and he sent me out a full set of replacements within a couple days. The second set have performed flawlessly for the past year.

I recommend them and recommend getting them through Performance Wise. Yes, I had an issue, but Paul was great getting it sorted very quickly and without me having to take my car off the road (I sent him the defective ones after he sent out the replacements).

    • What copper washer do you guys use on the bleeder bolts? The existing one I have I had no idea where to find it in a local store, I did buy some online but that are only 1mm thick whereas my old one is 2mm+ thick and when I put the new washer out and squeeze the top radiator hose I can hear a bit of air but not with the old one. Does this matter? The new one doesn't leak, but the inner diameter is a bit loose whereas the old one threads on the bolt.
    • Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason.    From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced.  Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms  other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!
    • No probs at all. I used to love trying to dig up obscure info for those in need where possible going back 20+ years on SAU.  I did have another look and couldn't come up with any closer match. I'm leaning towards those skirts in your first pic are custom fitments, cut down/extended or from another car entirely and modded to fit an R34 sedan. I would've thought someone in Japan had them and taken a photo at some stage over the last 2 decades but there's nothing. Someone out there must know surely.
    • Welcome mate. Any pics? Even with a DE I'd be well happy if I had that as a 1st car.
