If you can run the 1.1mm gap without it missing then do it. The bigger gap the better. People only reduce the gap when they are running large boost or have old, weak coils that can't provide a strong enough spark

That's true, only reduce gap if you have to.

NGK BKR6EYA. = 0.8mm

I was running these on 10psi with stock ECU. No Problems.

Installed an SAFC 2 and my Tuner gapped them down to 0.7mm due to old Stock Coils. No Problems.

NGK BKR6EYA-11 = 1.1mm

I will go back up to 1.1mm soon as I just bought some Brand New Stock Coils.

This will be interesting...

That's what I thought.. I will try the 1.1mm gap an see how I go. It only has 140k on the engine so coils might be fine.

Is 1.1mm and 0.8mm the only 2 gaps I can run or should I try lower the gap in 0.1mm increments like as in if 1.1mm doesn't work maybe try 1mm then 0.9 then 0.8 or is that pointless? I'm new to the whole boost scene so excuse my lack of knowledge haha appreciate everyone's help :)

If they are the original coils at 140kms then they will probably be getting a bit weak.

And yes, you can just drop the gap by 0.1mm increments until it doesn't miss

If you want cheap BCPR6ES, get them off eBay

Just buy more than 12 at a time and it works out pretty sweet, $2.90 each delivered

I just ordered 24 lol, works out to be $2.81 each.. :)

Well the 1.1mm gap works fine. Revs sooo much smoother now. Coils must be good :D Old plugs had a little miss before it revved. Doesnt miss at all during idle or rev. Have no driven it yet to test them under load but all seems fine. Thanks everyone for your help

I've checked alot of places and I can't seem to find BCPR6ES spark plugs with 0.8mm gap I can only find 1.1mm and super cheap say (after rego checko) they are not a right fit for the rb25. After alot of searching and doing my head in I found BCPR6ES with a 0.9mm gap from justjap so that's what I went with... ?‍♂️ Stock rb25

Hmmm. You just set the gap to whatever you want with a very cheap tool.

I use those plugs with 1.1 gap and have zero issues. Drop gap if your coils are shit, otherwise leave at 1.1

So why so hard finding info ? Gapping copper/nickel and platinum plugs is trivial. Iridiums are the only ones you've really got to be careful with. In NGK if it has no - prefix at the end it is like this-

# heat range.

Copper/nickel plugs, the bcpr#es is pregapped to 0.9mm / 36 thou, there is no 0.8mm gap in bcpr#es coppers.

Platinum plugs BCPR#EP and Iridium plugs BCPR#EIX, are pregapped to 0.8mm / 32 thou.

A -11 at the end indicates an 1.1mm / 44 thou gap as an option, available in all of these plugs.

Also 5 is stock NGK heat range for RB25, 6 for RB26.

Probably why Repco / Supercrap say it's the wrong plug too.

    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
    • Yeah, shame. Maybe  driver's carpet is available 🙏. I am waiting for both amayama and nangun to confirm.
