If you want to upgrade find an ITR TB, they are 62.. but make sure the IM is portmatched to the TB when you go bigger.

Re: (prestidge81)

straight boring or tapered? i have tapered a b18 to 65mm and a jdm b16a to 68mm but it does take alot of time to thin out the walls... i normally dremmel grind the TB with 60grit bands, then 120grit bands, then use a abrasive buff 220grit and then 320 grit and it comes out really nice.. its about 20 dollars in materials and like 3-5 hours to do it
