plug gap

Has anyone heard anything about changing your spark plug gap to a tighter gap for a turbo motor. I read somewhere that that was a good idea. Just wandering since im about to change my plugs this week.

Start at .030 and close it tighter until you get no blow out. I usually run .027 in turbo 300ZX's.

High boosted Hondas go down to 15 at times. Just depends on your boost and compression levels. Read up more about it and adjust to your own situation.
