spark plugs all motor
i know this is homemadeTURBO but i wanted to know if you should stick with the stock plug rating when dealing with a higher than stock CR on an all motor build or if you should change the heat range like on a turbo setup. is there a general rule for choosing a plug for a motor application? and what is the resoning for changing the plug? school me...

Re: spark plugs all motor
compression/cams/static compression etc have all a role
Im assuming your talking what 99 percent people do slap oversized cams in a stock motor with a poor flowing head,manifold and undersized throttle body because you heard volume was a waste of time according to h-t but a hondata intake gasket will make you king of the streets
stock ngk range

Re: spark plugs all motor
lol no im not overcammed iam pretty aware of engine dynamics even though iam askin the newb question on plugs. the motor i have is nothing crazy just a b18c1 with usdm itr pistons valvetrain and buddyclub spec3+ cams. blox im and 4-1 2.5 collector header with full exhaust. i had a portmatched TB but have been playing with the size i want to stick with since i feel its losing velocity and thus power for the powerband that the car is in right now. i just wanted to now if there was power to be had chaging the plug range since the compression has been uped a little. i appreciate the comments so far....
