I have a b20vtec turbo..I got some ngk-brk7e spark plugs what should i gap these spark plugs at?My ignition setup, i have a msd 6al w/blaster coil and managcore 8.5mm wires..

 

.36 should be fine. How much boost are you running.

 

about 9psi

 

I would think .36 should work for you. If you have it on a dyno and your curve isn't smooth in the top end then you probably have too much gap. I have been running .40 on pfr7g-11's for 2 years without a problem. That is only at 5 psi though. The more gap you can run safely, the better.

 

Just in case it a newb, it's not .36" but .036" plug gap. You never know how literally some people take a post

 

Lol, I never remember the 0 .
