spark plugs for boost
im getting ready to put a turbo on my f20. i was wondering if anyone had any info on spark plugs ie... do i need to go colder and if so how cold from factory. i will be running 10 pounds on stock compression with 750cc injectors at about 6000ft elevation. i already built the engine and head and installed kpro.

NGK, Heat range 7, plain copper plugs. 1.99/piece
Forget the model/part number of the top of my head.

This is something i haven't really looked into. I've been supercharged and i've been running NGK Iridium IX spark plugs. Soon going turbo, and i just plan to use the same type of spark plugs.

We prefer NGK Iridium plugs. They have been effective up to 750 BHP for us. We use no. 7 up to 375 BHP, and 8 above. You can find them here, along with a gap reference.

Most folks go with 1000cc ID injectors, however 750cc should get you your goal, but likely nothing beyond that.
