hey, I was wondering what the best intake system would be on a 87' N/A. Should I run a tube down under the car and pull air from there or just cut a hole in the factory airbox and sill it to the hood (make some luvers in the hood). My mass air flow sensor is so small though. It is not like a 89-91. Can I make one of those work or do any thing about it? I go the crap beat out of me by a built up civic with an SI motor. I have straight pipe with one high flow cat. will a header give me much more?
