52mm at the plate. Technically it's a little bit smaller, but I don't know how much. Probably a RCH. And all the 2000+ Neons have the same size TB.

Is the "49mm" due to the dovetail on the T/B plate ??

:withstupid: The bore at the throttle plate is 52mm, I just checked it a day ago. A 52 mm circle fits snugly at the throttle shaft holes. (It was a t'stat actually, I checked the diameter with calipers, even tho it has 52mm stamped into it) I can see the dovetail reducing the area by a few mm.

Edit: the inlet opening is 60 or 61mm and the outlet (bellows side) is 57mm

Probably shouldn't listen to anything your penis says, that guy's a dick.
Patience, of course, is a very powerful weapon, but sometimes I start to regret that it is not a firearm.
