Just want to get some opinions. I know that you cant beat the factory type
NGK plugs. just wondering which one to go with. Car has all the usual bolt
on goodies plus JUN cams and I am running factory compression. Cars is
always driven at the upper limit of the rpm band. Mainly a lot of road
racing with the car. Always use 93 octane gas or better. Should I go with
the stock heat range or a range colder/hotter. just want to get some
opinions. THANKX!!!! (too bad JUN doesn't make spark plugs:))

1991 SE-R (too many goodies to list)

I've gone with one heat range colder than stock. Actually, I've got the "original" heat range for the SE-R. From the stories I've read/heard, they replaced the plugs with one heat range higher after the first few shipments from Japan arrived with fouled plugs due to contstant starting/move 20 feet/stopping during loading/unloading from the ship.

I haven't had any problems at all.
