Spark Plug Gaps

[S15_Spec_R]

I have searched the site but no conclusive answer.

What I would like to know is what gap should I be running, the car is at 1.15bar and has been mapped. I currently have a gap of .75 (as they came) but have heard/read that .9 (nissan standard?) and even 1.00 should be used.

I am using NGK BKR8EIX plugs as that is what someone on this site says to use for more than 1bar of boost.

Thanks, Keith

everything you have is fine, you need the smaller gap particularly when running higher boost

Thanks, so stick with .75 or nissan standard .9?

 

[kieran@silverback]

sorry dude, yes the ,75 would be the one to go with

.8 mm is normally a good starting point for anything over 1 bar so i think you are on the mark with .75

0.8mm upto 1.3 bar, then 0.7 over that upto 1.7 bar.

I regapped mine last week and had the same problem finding a guide! haha. I went halfway between the 0.9 and 0.75 so mines around 0.8 and runs fine
