Haha! That's a new one on me! Mullet gen..
I never really spent all that much on the Integra, but the guys I hung out with had spent thousands on theirs. One of the local guys built a 450hp turbo motor. While impressive, it sounded something like a weedeater with a blower.
Fell in love with the sound of a wicked hot cammed V8 sound, and never looked back! I don't care that it's grossly inefficient compared to some of the better 4 cylinder designs out there, I just love the sound and feel of a 500 hp supercharged V8 screaming past you.
