Rich.2211 Posted July 28, 2013 Share Posted July 28, 2013 I've fitted NGK 6097's gapped to 0.9mm in my NA-T Supra. The 'spark plug guide' says that is ideal for a BPU upto 1 bar so does the same apply for a NA-T with a T61 turbo? I'll be running 7.5psi at first then upped to 1 bar a few weeks after. Just want to confirm I won't need to close the gaps up any further before I bolt the throttle body back up. Any helps appreciated as ever Quote Link to comment Share on other sites More sharing options...
David P Posted July 28, 2013 Share Posted July 28, 2013 (edited) Close them down to 20 thou or the boost will blow the spark out. Edited July 28, 2013 by David P (see edit history) Quote Link to comment Share on other sites More sharing options...

Okay David I shall take your advice and re gap them to 20 thou. Cheers Edit - gapped today at 28 thou, shall bring the gap down if I start getting ignition problems with the spark blowing out.

ballsdeep Posted November 1, 2013 Share Posted November 1, 2013 How's the spark holding out..? Re-gapping mine tomorrow but never done it before, grabbed the feeler gauge from work and it reads .028 711mm does that sound about right?

Fly Posted November 1, 2013 Share Posted November 1, 2013 Regapped mine to 20 thou works a treat Quote Link to comment Share on other sites More sharing options...
Rich.2211 Posted November 1, 2013 Author Share Posted November 1, 2013 No issues at 28 thou but will bring the gap down if I get any issues when I increase the boost. Quote Link to comment Share on other sites More sharing options...
