The stock spark plug gap on a sr20det is .036 or 0.9mm...You wanna close the gap alittle the higher boost your running.

Re: sr20det spark plug gap??
15+ years later this old spark plug gap info is still ok BUT i have to tune a lot of cars running MUCH higher boost now days. On anything running ~20psi + (SR/RB/KA and non nissan engines alike) we will run R35 coils or IGN1A coils and copper or Iridium plugs gapped way down to 0.024". At 30psi+ gap may go down to 0.019.
This article breaks down SR20det spark plug gap and Plug heat range pretty well.
