My understanding is that it's the basic advice for most cars. Have a gander at the spark plugs thread, it's pretty long but there are a lot of testimonials. As I said, everyone's experience seems to vary. But most seem to think that coppers are the way to go and though they may last longer changing them every 5000km is safe. Just doing it with an oil change. It's not hard to do with a bit of practice, gives you some regular feedback as to how the car is running and how each cylinder compares to the others.

Most importantly, if you use coppers and change every 5000km the ignition system works, and does so at it's best. So even though some people get hundreds of thousands of kms out of some cheap platinums, and some people get only a few thou km out of high priced iridiums, coppers every 5000km works.

What plugs are you using george?

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This is an outdated statement as everything is made in China these days.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

General rule is run as bit as you can. Bigger gap means a more aggressive spark directly igniting more fuel. You might need to experiment, though someone on here might have better advice.

Note though, the more boost you run the harder it is to cross the spark plug gap.

yeah, if they missfire, just reduce the gap by 0.1mm each time until there's no missfire. then you know for next time.

i was running 1.1mm on 14psi with new yellow jackets. no problem.

In true noob fashion I don't actually know... :whistling:

They were put in by the workshop when I got my car tuned. They mentioned that the old ones where starting to show signs of wearing out & could cause problems with the boosted power levels later on.

I didn't mind seeing they just charged me according to my original quoted price & what ever they put it, it have being holding well for ~20,000kms.

So guys what's the general consensus on the yellow jackets now? Still running ok? I'm in need of new coil packs...

+1 for Yellowjackets

Had mine in for ~8months and 20,000km now after the old ones started to die. NGK Platinum plugs gapped to 1.1mm, no woes, now running 5psi and still good. smile.gif

got a set in my r32 gtr, no probs running 1.1mm spark plug gap @ 18psi boost :)

Still going strong for me.

Mine are still all good :)

Had my YJs in my daily for over 2 years now and they're still going strong.

That's the most direct and convincing question-answer sequence I've ever seen hahaha

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.

      High temp brake fluid?

      By Komdotkom · Posted

      Reasonably hard, although I haven't run it with the new Endless setup yet. The old brakes were F50's on 335mm rotors and the car did a 1:40.6 at Phillip Island which is a reasonable time, I'm seeing high 600s on the temperature paint. A guy I know ran the Endless fluid at WTAC without issues and he was doing 1:33's I think (Evo) with a 355/332 setup. I don't get out to the track as much as I'd like but we put the car on the hoist and spanner check every bolt and re-paint mark everything, bleed the brakes, change the fuel, check the coolant system and re-bleed blah blah blah before every event. Motorsport is expensive, RB's are expensive so a couple of hours before an event is time well spent. It's also a net time saving because if you can keep your RB from self destructing it saves you time in the long term!

      Hello! I'm new here, I have an R33 GTST that is currently being finished up! Last year was pretty rough, blew two stock turbos so I decided to build the car. Has been down since November, but I get it back next weekend!

      Hello, I believe my car was imported to America in the 2000s by Kaizo Industries. Would anyone be able to help me find more info on them? I've only found all the basic stuff like that paul walker bnr34, them being shutdown by feds, just stuff like that. Any help would be much appreciated, thanks!

      HKS Vcam Step Pro Issues

      By believer · Posted

      I am using Motec M150.  I am not working on the car myself actually.  My workshop is giving all these info, they are quite reputable in the industry and are very familiar with Motec and RBs and have done a few big setups with VCam and single turbo on RBs.  In fact, they built and tuned my engine from day one.  But they are stumped with my engine at the moment and cannot work out how come the compression is so low with the VCam. They told me that they have now swapped in some Kelford cams (without the VCam) and can achieve around 130psi compression and the low end torque is better, but now the engine is doughy as.  It boosts and peaks at more than 1000rpm slower, with twin HKS GTIII RS, it doesn't get full boost until over 5000rpm. I have always thought the VCam was a bit disappointing at the low rpm. To a point I had to ride the clutch a fair bit to get up a small hill from stand still.  That was when I had a clutch.  Now changing to a 8HP, I don't have that luxury and this problem has become a major issue. I am beginning to think the VCam never work since the day it was installed.  Maybe it was just sitting at the most advanced point, that is why it went good at top end but very ordinary at the bottom.  Therefore, with the help of the Holinger 6 speed and paddle shift, as long as it was moving, it drove pretty good.
