by taking out material form the overall inside diameter of the throttle body and replacing the butterfly plate to match.

like for example, lets say the oem diameter is 48mm and you get it bored out to 52mm or 54mm that would increase the amount of air going through the throttle body and into the inlet manifold.

I remember seeing over sized ones for B18A's at something like 75mm for like $285.

180sx: nope dont think it does fit, the mounting points are different and I think the withs are different too?
