What spark plug, and what spark plug gap would you reccomend for a 300 ZX TT running a forged engine, with GT525 turbos, and a Nitrous system, please bear in mind the nitrous is only used ocassionally at the drag strip, and introucdiced via  minimax controllerr. The car also runs Link G4 + ECU. 

Thanks

I would contact Greg Gush at Protuner for advice. I recently had a Link G4X ecu fitted with them and they knew instantly what heat range spark plugs I should have and fitted them for me to suit. If you give him your engine spec as per your post, he should be able to confirm. Failing that, ask Jimmer at PowerZed.

I would recommend NGKBR8EIX iridium, I recently installed NGKBKR7EIX in my Zed which is running approx 380 bhp.

I took advice from here, (Concept Z) :

Was slight typo error... I would recommend NGKBKR8EIX?

Unless your engine is tuned to within an inch of its life, stick with the OEM recommended plugs......

I've always run 7 or 8 heat range iridium's and they have performed well on slightly modded Zed's...
