I have a stock z6 with a 14b on it. i am detonating real bad whenever i give it more than about 3/4 throttle. i am going to run some higher octane, i have 89 in there now, and i am going to throw some octane booster in the tank till i fill up again and can get 93. but i also understand i need colder plugs. what plugs should i get? i guess a part number would work, so i can try and get them from the autoparts store up the road. i know i want NGK, and i told them 2 steps colder, but they didnt really know what i was talking about.

I'm using bkr7e-11s

They are actually the copper NGKs that are the heatrange and gap for a type R.

Hey NooB how about you tell us what fuel management you are running? That may help.

djfob

this would be nice....you really only need one step colder zfr6f-11

hey DicK, and others, i am using turboedit. what difference does that make? and i had NGK BKR6E's in it, are they ok or no?

SpankedYA!

Ok -------, if you are using Turbo Edit then stick to the stock plugs and tune it. But by the looks of it that will be way beyond your realm of thinking. If you are using an FMU then I would drop a range. And remember **** WRANGLER I'm not the one asking stupid ------- questions. Your ------- post was incomplete. If you posted your whole setup like a normal person would do you wouldn't get flamed!

ok, i forgot what i posted i thought i just asked about plugs. so ima dumbass, but i am using turboedit and i did just use a basemap. but it should have had too much fuel, and i dont have a wideband yet, is there any other way to tell if its running to lean? and the o2 sensor wouldnt matter at WOT would it? and the bkr6e's should be fine.

SpankedYA!

THe only way to tell if its running lean or rich would be to constantly pull them and look at them. That won't be consistant though. You really need to hammer out the A/F with a wideband or a dyno.

Please bear with me, as I'm kinda an amature to doing my own work, but learning quickly regarding the nature of the beast. But I would ask the same question: What kinda plugs should I use?

Setup is in an '89 CRX Si that includes a D16Z6 still using the damn OBD0 and stock ECU with an early 92-95 Civic EX GReddy turbo kit, using a Paxton FMU. I gather than NGK-Rs are good? What number should I use? Please don't flame me, I'm learning fast.
