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?

      Possible swap on R34 RB20DE NEO?

      By GTSBoy · Posted

      If the RB29 box in the car is a push clutch, then yes, you will need to deal with the pull clutch on the turbo box. You either buy a pull clutch and don't use the old one, or you do the things needed to convert the turbo box's clutch arrangement over to push. Which is a bit of a f**karound. "Making" a custom tailshaft is the easy part. But you will need to source the front clip yoke - the bit that goes into the output of the gearbox. These are not as easy to find. They are out there, but they don't grow on trees the way that they used to.

      Turn signal wiring question

      By GTSBoy · Posted

      Indicator bulbs are way too bright to use as a "corner marker" (we call them parking lights too). Sure. Go ahead and do it. But realise that you wil need to come up with all your own wiring to do it, as no-one will have a standard howto worked out for Skylines. It's just a matter of abandoning everything that Nissan have done and starting from scratch. You'd probably be better off retrofitting tailght/brakelight globe bases into the front indicator housings and using the taillight circuit for your corner marker and the brake light as the indicator. You'd need to work out how to kill the marker circuit while the indicator is flashing, otherwise it won't flash on-off, just bright-less bright.

      Possible swap on R34 RB20DE NEO?

      Hi. A little bit of an update. It maybe(hope not) looks like i would need a new tranny(it would be "maybe" a cheaper or better option anyway) So i need some info. I know i need a different propshaft(i can make custom one) LSD is not a problem cuz the engine will be still(for now) N/A RB20. So if i buy RB25DET NEO tranny...is there something else i need? I read something about push/pull type but i do not know if i need to "change" something or i can just plug n play onto my engine a go? Thanks for the advice

      Turn signal wiring question

      By OakvilleGTR · Posted

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance

      Mistakes were made, my R34 Story

      My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..
