Whats the heat range number?I run a very similar combo and I'm using ngk r plugs gapped at .030". Works very well for me, I've put around 10k street miles and 2 full seasons at the track with no problems on 12 psi.
same here, but haven't completed my install yet. These are what was recommended over on the Turbo Forums and by Rick of RNHI run NGK R5671A-8 in mine at 10 psi
