Some of the holes on the yellow jackets have epoxy or something in them i took a philips head screwdriver and scraped it out, coils fit perfect.

Hey guys, I run a set of the yellow jacket coil packs that Performance Wise offers. To set the scene, picture an RB30 block, built to "nissan spec" (Now, I use this term loosely, as the whole motor

Not true for Yellow Jackets. We tested the YJs thoroughly before releasing them to the market. Not just in the factory, but on the street and the track, in real life circumstances. Im still in contact

This is an outdated statement as everything is made in China these days. My Yellow Jackets are made in china and I oversee QC and work closely with my factory and now, 5 years later, and over 2000 se

I've fitted a set of Yellow Jackets the other day along with new spark plugs aswell gapped to 0.8mm and took it for a 'hills test' - and my god, the car drives absolutely beautiful, very smooth, straight to redline no hesitation no nothing, feels like a whole different car! I cant remember the last time the car has driven this well!

I dropped mine in with a replacement harness and new plugs gapped at 1.1, not missing any more and feels to have a meatier mid range, but probably just my imagination.

Why is everyone going straight for a closer gap?

There seems to be a bit of a consensus that anything above 0.8mm can result in misfire. I'm gapped at 1.1mm with no misfires, but I guess if it's solved peoples problems then we can't question it :laugh:

I say leave it at 1.1mm and if you start to develop misfire then re-gap.

I left mine gapped at 1.1mm also. Just new coilpacks fixed my missfiring. IMO if you need to gap down your plugs your ignition system isn't up to scratch.

Smaller gap = Weaker spark

Larger gap = Stronger spark

This man he knows^...

i went the already gapped iridiums at 0.86. Since JJR replaced my faulty coil pack it hasnt missed a beat.

I was thinking whether I should leave them at 1.1 or go down to 0.8 but then thought didnt want to risk any missfiring and having to take things apart again - it gets tiring mucking around with the same thing over and over again... but it drives perfectly now no problems whatsoever so its all good either way. I'll probably give 1.1 a go next time see how that goes anyway.

i fitted my yellow jackets the other day. it was time for new plugs, so i swapped out my 0.8mm coppers for a new set of 1.1mm.

13psi, no missfire, at all, at 1.1mm!!! my old coilpacks had no missfire either, but needed 0.8mm to get that result.

for the price, you cant go wrong. and Paul from performance-wise is a top bloke to deal with. very pleased all round.

on a side note. my logic says if you can run 1.1mm without missfire, then you'll have a bigger bang, better burn, and optimal conditions.

yet i have heard many people say if you are running higher than standard boost, you need to run 0.8mm, regardless.

why? i just dont get it.

just ordered the Yellow Jackets. Cant wait for them to arrive.

I did the DIY to my oem coils (wrapped and silicon the coils) and replaced the plugs with NGK copper V power Heat range 7 and re gaped to 0.8. The car was still miss firing at 5k RPM and wouldnt let the car boost over 0.6BAR

I have HKS2530's with the actuators set to 1.5Bar.

I'm going to try and just drop the yellow jackets in with the spark plugs i have now with the 0.8 gap and see how it runs, if not then I will buy some plugs with a 1.1 gap....

I made this argument a couple of years ago in one of the spark plug threads. No one listened to me :bunny:

My NGK Iridiums are coming up onto 60thou kms and still running strong and good condition after recent inspection. Stuff coppers, I'm not into changing every 10thousand

to be honest, i like changing my plugs every 10k kms. lol

gives you the opportunity to check their condition, spot any warning signs, and give the whole area a once over.

i'd feel weird not looking at them for 100k kms, if they infact would even last that long.

bit more feed back for superspark. Had mine in for about 5000kms , including 1 track day. plugs gapped at 1.1mm. havent had any hint of even a slight misfire! product fitted exactly as per the oem items.

I'm yet to increase boost up yet, will post once i have.

ALSO 12 month warrenty on super spark... not 2-6months as previously stated.

      You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before

      OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:

      R34 manual conversion speed signal wire finding, need help

      By GTSBoy · Posted

      Yes. Autos typically work from the speed sensor on the pinion shaft of the diff. I also think that even if you have a proper speed sensor for the bog manual in the manual box, that the signal it outputs is not compatible with the auto dash anyway. You should consult that manual (the book, not the gearbox).

      And I just realised that that advice is slightly nonsensical for a GTR, because you need 2 of them. But it is otherwise true.

      Duncan's V37.......race car?

      By Duncan · Posted

      Having had a reasonable look at the car, I'll be able to remove the (one time) rams and retract the hinge (they are held in the down location by a tiny (m3?) sacrificial screw) which will get it physically back in shape. From there if you remove the rams you need a resistor to turn off the airbag light (as Mark said, there are plug in kits and I might go that way because its reversible). And...per all the threads on here, even if you have the resistors to turn off the airbag light, the bonnet light will stay on as it writes to the airbag computer history - that is either replace the airbag controller, reprogam the EPROM (if I can work out how), or remove the globe from the dash. Having seen how sensitive this system is, if I had my time over I'd pre-emptively remove the rams, even on a road car, because this is all a very unnecessary pain in the arse. Reminds me, time to go and have a look at the Fuga too....
