B18a1 Throttle Bodies??

[rikiewrx]

Curious to know if there are any larger stock tb's that would directly bolt to a B18a1? Or maybe bolt on with the help of an OEM Intake mani found on other B series.

Thought the b18b is like 60 and the gsr is 60 and isn't itr like 62mm?

Either way if your going to get it new, you'd be better off buying an aftermarket one in the size you want.
