What is the diameter of the stock IM opening (b16a)? I found a good deal on an ITR TB (which is 62mm I think) and I wonder if I have to port the IM opening (which should be at least 60mm, like the stock TB I believe).

Thank you very much for the reply. What about intake manifold diameters. I suppose they are not exactly the same with the TB used. I would like to know the b16a2 and b18c5 (R) IM diameter (I think skunk2 opening is 65mm).
