I have a 1992 B13 SE-R, I've got a generic MAF adaptor Spectre Racing Cone air filter set up right now (the MAF adaptor is a Weapon R, had a Weapon R filter that the previous owner didn't clean, so I got what I could afford) Anyway, I have roughly $140 I can spend on my car this month, I want to buy a header and change my MAF adaptor to a different type, I saw the site for the BP flowstack, its cheap, but is it good? If so, I'd be able to buy a header and that with what I have to spend. Otherwise, should I invest in a Jim Wolf unit and wait on the header, or get the header and just live with what I have as intake? What is my best performance per dollar deal?
