      H22 and ITR are bigger, but only 62mm!

      Send it to www.Maxbore.com and have it bored out for $100! Mine was done to 64mm!

        Sweet! I'm putting that on my Xmas list

        Is there a noticeable gain with this mod? Are the aftermarket TBs bigger than 64-65mm? Is it better to do this or go aftermarket?

        Tks

          I think with your mods, all you need is a type 'r' style intake manifold. Unless you build your motor more you shouldn't have problems with air starvation. Just poor flow. TB won't help as much as IM.

            b20z TB is 62mm

            and it will cost a lot less than some ITR one

                I think you should send it to Jorge at Maxbore.com. He is located in florida and has a one day turn around time! Also you can still use the sensors you are currently using now!

                I'll vouch for him that he does damn good work! He did my TB!
