Ok, im trying to make a custom turbo inlet duct, (not for an integra, sorry) and i was just gonna get one of those generic ebay intakes and modify it to fit. The thing i need to know is the diameter of the piping, and i cant get a straight answer out of these ebay morons so i came to you guys

I really need some 3" diamater piping, anyone know the dimensions of the integra TB? 2nd and/or 3rd gen would be great, thanks
