I know this isnt the WTB forum but was hoping to get some visibility
The stock pulley on many kits is 3.8 or 3.9in and thats what I am looking for. My pulley is 4.03 so the 3.8 or 3.9 (whatever it is) would be great for a very small increase in boost.
Let me know if you have one, I have a 3.6 I could trade you.
