49977, quick TB question (honest)
Posted by DR1665, Apr-28-03 11:58 AM
I tried searching, but to no avail.
The stock 420A throttle body inner diameter is.....? 50mm? 55mm? 10mm? 12mm? TIA!:7

The butterfly plate is 52mm...but there is a restriction right before the butterfly plate which only opens to 46mm. So essentially it is 46mm.

Apparently SOMEbody's been spending time away from the board. :P
Thanks for the answers guys! :thumbsup
I'm gonna be a cheap-skate and port & polish the OEM. Looks like I should buy some more grinding bits and SimiChrome...:7

Ahhh. It's not so cheap-skateish. Round it out to 52mm - a few people have done it and really liked the results.

EDIT: a course, I'm stickin with the 60mm Jeeper :)

im sorry guys yes i have been away from the boards i finally realized the on people on dsmtuners with an NT motor are mostly idiots, i stress mostly. but there are the chosen few who are geniuses (sp. im an idiot) I Now know that this is where everyone went... Im just learning how to use this board, i think its harder than dsmtuners. but i will be around posting what i know and learnin what i do not.

If I remember correctly, it was 52.5mm. but it bevels in on the inside so it's significantly smaller
