# TB boring...

Posted by James (2 VE's) on September 10, 2002 at 18:08:12:

What's the stock size on the TB? I was reading thru Don's mod list on his VE and he had his TB bored (71mm)...

Also *scratches head* what happens with the butterfly valve inside the TB when it gets bored out?

- Post yesterday on .org about this on a VQ. price is around $150 or so for labor. they use a new butterfly valve too, btw. nm Matt (93SE) 00:23:20 9/11/2002 (0)
- I am also thinking about doing this one day. I just have to do more research. Good question BTW. n/m Aaron (92 SE Auto) 23:19:05 9/10/2002 (0)
- Well on some TBs, like the VG, the butterfly is a larger diameter than the TB on either side by like 2mm. It slopes in and out. n/m Kaleb (Black '93 GXE 5spd) 18:49:20 9/10/2002 (0)
