which spark plug?
it mainly depends on the tuning.
What year is your b6t from?
Is it from a 323 or a capri? The capris used the miats rods so id say 250 Safe HP. Though people have pushed upwards of 300 i say 250 is nice and safe. Though the 323's were beefier by alot so 300 should be easily capable.

Personally I just run the NGK V-Power spark plugs gapped to .032" and recommend changing them every 3K-5K miles depending on the plugs condition (visual inspection).
Get the stock heat range plug or one step colder for a 88 Mazda 323 GTX
If you run conservative timing advance or throw enough fuel to it then you usually don't need to run colder than the stock heat range. If you want to get technical you'ld have to start monitoring EGT's, AFR's, RPM, and keep visually checking the plugs to see how things are combusting. Basically if you can't keep your EGT's under control with fuel tuning then you need to consider running colder plugs. I have yet to need to do so and our daily driven BP sleeper is making around 230WHP. My drag car will probably need a few steps colder due to the insane cyl. pressures I'm going to throw at it with pump gas on the street and C16 on the track. I'll probably run hotter plugs on the street for driveability and gas mileage from more conservative timing maps and less boost pressure.

In my experience just run a step colder plug.
I had stock heatrange plugs in my car for about 10 minutes and It backfired like a motherfucker/ran like a--.
im only running 12* at the disty and my afr are no higher than 12.3.
Though i know JW has more expertise, Im just relaying my experiences.
Though my question is Why with only 12* of timing. Ive read up on some honda setups and there running upwards of 18* of timing with A good amount of boost.

so i dont hafta go 1 step colder cuz im getting an air fuel ratio gauge and well im gonna be running advanced timing but im not sure how much and well see me and the parts guy were at the counter for like half an hour trying to find a plug thats 1 step colder and well we couldnt find 1 and he said if i could ask some1 for the number off of the plugs that they have in there engine it would help us out ALOT and make it alot easier. so if some1 could just tell me the number off of the plugs thatd be great unless i dont hafta go a step colder so i just really need to know cuz i plan on running 12 psi so if some1 couldhelp me out thanks. sorry if im being a pain.... i just wanna get the car going again its been almost 2 weeks already and i miss her.........

I run bkr7e-11's in my bpt. I had a problem with the spark being blown out at 15 psi so I gapped them to .030 and it was fine. What you have to do is take the car for a good run then check the plug.. You can look at the very tip of it and see how good the heat is on it.. It should be a slightly different color right across the top until it reaches the turn then stop. If its just barely there then the plug is too cold and if the whole thing looks discolored then its too hot. I use 7's though... Just to be safe.. its all the same price anyway and my plugs look perfect.
