So I am in the market for coilpacks as apparently I have a missfire problem, can anyone tell me how I can test WHICH coilpack(s) is faulty in my R34 NEO??? Meaning later down the track if I need to return a failed coilpack under warranty that I just bought, I do I find which is the dud one?? cheers

Depends on what's wrong with it. Try checking the resistance of the primary coil in each one (you'll need to know which pins to check, and i'm not even sure if its possible on integrated ignitor coils like you have - depends on how their wired internally). Other than that, look for any arcing, which will happen if the insulation is flawed. Many people fix arcing issues with silicon or electrical tape. Search the DIY section for details on the insulation fix.

Thanks mate ive done the taping of my coilpacks already with high quality silicon tape and it still misses bad so its definitely not an arcing issue but the internal coils are shagged, just need to find out which one..

lol well if you want to break the answers up, I did have a problem with one YJ coilpack after about 20,000km...but PW replaced it for me...then another went after that and they replaced that for me. Haven't had issues since. That's the kind of after sales service that puts my mind to rest when considering products. Would I buy them again? Yup.

It appears that from a warranty perspective...

* Yellow Jacket will honour w'ty

* Superspark will honour w'ty

* With Splitfire, it's like pulling teeth

I think your Q is directed towards Birds.

Usually, one initially looks for a flared scorch mark around it's body emanating from a pit hole that may be visible; perhaps not.> indicates arcing as Adam said.

If a couple in that set are gone, it's best to replace all.

Hey guys dont mean to bump an old thread but thought ide ask anyway.

Ive had my drift car for about a year, have only taken it to the track about 5 times so far, its an r32 gtst, rb20det, nistuned @ 15PSI and making 240ish RWHP, i pretty much am limiter bashing this thing at the track most of the time, hitting 6500-7500rpm regularly.

twice at the track its cut out on me, feeling almost like it completley turns off mid drift for a split second and splutters like crap shooting flames out of the exhaust.

So my question is, out of the 3 or 4 main brands out there including OEM, what are the actual BEST items that survive the most punishment, im not worried about price i just want a good product, im leaning towards OEM but am worried that OEM once might last the longest for normal driving but not for drifting or thrashing?

They all perform much the same and have the same failure rate - search all brands and you will see success stories and issues, so there is no "clear winner" brand to go with in terms of expected longevity in a modified car. Consider also, that most people who buy aftermarket coils don't have issues with them and you won't likely hear from them - it is naturally going to be the 1% or so who DO have issues, who will come on here complaining or asking for help.

IMO, go with a brand that is likely to help you out should something go wrong down the track...the last few pages will offer good insight into this.

Sorry to bump an old thread, have found a genuine OEM coil pack seller for $320 PER SET (which sure beats $190 each) have also found new coil pack looms for $100 delivered.

I am not tossing up between YJ ($420 set) and OEM ($320 set) I've just read this whole thread, confused with some contradicting statements regarding OEM vs SF vs YJ for high hp applications.

I'm of the mentality that std parts are good for std power, what are thoughts on longevity of OEM coils 400hp+ ?

Id be very suspicious of a set of mew OEM coils for $320/set. They are most likely fakes.

I run YJs and have done so in 2 different cars for over 4yrs now, They arent extreme machines. My older stagea, which had a mild 380hp and my R34 GTR has around 460hp and the YJs are perfect. Ive had the YJs in the GTR for around 2 months now.

Theres heaps of guys on here running YJs at over 400hp and have done so for a while now without any hiccups.

Sorry, they are fakes. Have a good close look at them. There are imperfections all over them.

You can get these same copied coils in Hong Kong: http://www.alibaba.com/product-gs/380257087/NISSAN_Skyline_R33_Ignition_coil_pack.html

you won't be the last person to buy a knock off with a genuine part number.

good luck however. good call if they are real but I highly highly doubt it

Have a look at the item number, the bloke is adamant their genuine, if not i guess I could always return them using PayPal?

Just saw this, you mean with the nissan logo/ stamp?

yellow jackets here I come

Basically, all coils are copies of the OEM ones but this is the worst when they try to pass off a product as genuine by stamping Nissan logos etc all over them.

They go to great lengths to do this.

I dont know why they dont just come up with their own brand like Superspark, Splitfire and Yellow Jackets have done.

I've been using Splitfire coils on my SR20DET and they work great...more stable and strong spark. gotta be careful when dealing with electrical stuff... get quality products and not cheap knock offs esp china made ones.. =)

    • The engine stuff is Greg Autism to the Max. I contacted Tony Mamo previously from AFR who went off to make his own company to further refine AFR heads. He is a wizard in US LS world. Pretty much the best person on earth who will sell you things he's done weird wizard magic to. The cam spec is not too different. I have a 232/234 .600/603 lift, 114LSA cam currently. The new one is 227/233 .638 .634. The 1.8 ratio roller rockers will effectively push this cam into the ~.670 range. These also get Mamo'ified to be drilled out and tapped to use a 10mm bolt over an 8mm for better stability. This is what lead to the cam being specced. The plan is to run it to 6800. (6600 currently). The Johnson lifters are to maintain proper lift at heavy use which is something the LS7's supposedly fail at and lose a bit of pressure, robbing you of lift at higher RPM. Hollow stem valves for better, well everything, Valve train control. I dunno. Hollow is better. The valves are also not on a standard valve angle. Compression ratio is going from 10.6 to 11.3. The cam is smaller, but also not really... The cam was specced when I generated a chart where I counted the frames of a lap video I had and noted how much of the time in % I spent at what RPM while on track at Sandown. The current cam/heads are a bit mismatched, the standard LS1 heads are the restriction to power, which is why everyone CNC's them to get a pretty solid improvement. Most of the difference between LS1->LS2->LS3 is really just better stock heads. The current cam is falling over about 600rpm earlier than it 'should' given the rest of my current setup. CNC'ing heads closes the gap with regards to heads. Aftermarket heads eliminate the gap and go further. The MMS heads go even further than that, and the heads I have in the box could quite easily be bolted to a 7.0 427ci or 454 and not be any restriction at all. Tony Mamo previously worked with AFR, designed new heads from scratch then eventually founded his own business. There he takes the AFR items and performs further wizardry, CNC'ing them and then manually porting the result. He also ports the FAST102 composite manifold: Before and after There's also an improved racing crank scraper and windage tray. Helps to keep oil in the pan. Supposedly gains 2% power. Tony also ports Melling oil pumps, so you get more oil pressure down low at idle, and the same as what you want up top thanks to a suitable relief spring. There's also the timing chain kit with a Torrington bearing to make sure the cam doesn't have any thrust. Yes I'll post a before and after when it all eventually goes together. It'll probably make 2kw more than a setup that would be $15,000 cheaper :p
    • Because the cars wheels are on blocks, you slide under the car.   Pretty much all the bolts you touched should have been put in, but not fully torque up.   Back them off a turn or two, and then tighten them up from under the car with the wheels sitting on the blocks holding car up in the air.
    • Yes. Imagine you have the car on the ground, and you mine away all the ground under and around it, except for the area directly under each individual wheel. That's exactly how it'd look, except the ground will be what ever you make the bit under each wheel from
    • Yes, if you set the "height" right so that it's basically where it would be when sitting on the wheel. It's actually exactly how I tighten bolts that need to be done that way. However....urethane bushes do NOT need to be done that way. The bush slides on both the inner and outer. It's only rubber bushes that are bonded to the outer that need to be clamped to the crush tube in the "home" position. And my car is so full of sphericals now that I have very few that I need to do properly and I sometimes forget and have to go back and fix it afterwards!
