so i'm running on fu(kedout r33 coils... in an effort to stop the missing nige @ racingline has gapped some BCPR7ES plugs to 0.6 and it has run flawlessly for a year...

BUT

the miss is returning... i'm guessing that 30,000 later the plugs are shot (logical really)

i have splitfire coils sitting next to the bed...

can i just install the coils, plut new plugs in and not worry about a tune if i gap them back to 0.6?

or should i try the 0.8 gap first?

the car has a visit to uncle benno for the new turbo to be tuned up but that's not for a month or so

well standard gap is more like 1.1, anything lower than that costs you power because the spark is weaker. 0.6....that's really small and very much a band aid solution to a spark problem. Run it at at least 0.8 with the new coils for sure.

      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)
