Hey guys,

I have an R34 with a 25det neo with fmic, pod, ebc, exhaust and im running the standard ecu. My issue is that im getting a miss at about 1000rpm when im in neutral with approx 5-9% throttle. its a quite noticable pop-pop-pop with no smoke from exhaust, also when im slowly moving in first, again with very low throttle percentage i get the miss,which quickly goes away with some more throttle, I am getting coils replaced soon and have recently done plugs less than 500kms ago and same with oil, coolant etc. Would the coils be the cause of this issue or could there be another problem that I have overlooked...

Thanks in advance,

coils probably arent the issue, when coils go they tend to misfire under high load/boost/rpm. your problem could be a number of things. i'd agree with adriano, check the ecu fault code and go from there. if you take it to a garage make sure you take it somewhere thats experienced at specifically diagnosing these types of faults. i've even seen nissan dealerships mis-diagnose this kind of thing.

      What should I do next to hold the head on

      Possibly avoid using a Cometic one unless the deck/head surface are perfectly flat. I did have a look just then and forgiving gaskets such as Tomei or Nitto don't exist for the FJ20, however the Bar-Tek or Kameari ones look good and might do the trick.

      Because pipe threads for pipe things. M threads for bolt things. Throw some teflon sealant onto it and dust your hands off knowing you did the right thing, instead of going twice around the block to achieve a result using the wrong things. Of course, all of these solutions are ignoring the fact that the minimum thread pitch we're talking about here is 1.25mm, with the 1/4" in NPT or BPS being out around 1.4mm. You will need to know that the boss you're tapping has enough thickness for at least a few threads. That's one of the reasons that 1/8" is commonly used - because the pitch is <1mm. And why would you look to use 1/4" NPT in a BSP country anyway? Ugh.

      Just throwing around ideas, does it need to be in the compressor cover? Why not the hot side piping?

      1/8NPT drill size = 8.7mm. Since the hole got messed up by me, it’s probably around 9mm.    So 1/4” NPT would be next step. A drill size of around 11mm would be preferred there which is not way of my M12 (drill 10.5mm and tap M12 threads)
