I have changed my spark plugs, gepped to .08, siliconed my coil packs and all that and I still get a miss fire every once in a while when my car is warm. Is there anything else I could do to stop this? My power fc is coming in tomorrow, will that fix it? It's nothing bit, it just bothers me.

not always does the siliocn trick work so its probably still your coil packs. (did it on friends r34 twice and it failed so bought spitfires)

either try siliconing it again or purchase some aftermarket coilpacks

I had the same problem with my car (RB20DET) and i innitially thought it was the ignigtor overheating. Like you it only happened when the car was warm. But after putting my car on a scan tool at Nissan and coming up with no errors it was narrowed down to a module that even the scan tool can't pic up, which turned out to be the coilpacks. They were 15+yo after all. So i bought some splitfires off Sliding Performance off this site (link below) and chucked in some new plugs while i was there (old ones had done about 10,000km) and problem solved. The coilpacks were $485 delivered and took around 5 days to arrive. Hope this helps. Good luck. :)

Yeah, I tried the silicone job on mine - fixed it for a little bit (might just be the placebo effect), but then back to it's old ways. Replaced them with some younger coils and it's happy again! I'd ask someone if you can use their coils as a test, just to be sure it's not something else.

so younger OEM coils can fix this problem aswell? spitfires aren't REQUIRED?

      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.
