Soon, Ill be installing an RRC intake manifold with a Toda Big TB.
Now the Toda TB has an outlet of 66.5mm and I believe the RRC inlet is 64 or 65mm (waiting on delivery for the RRC).

I'd obviously prefer not to bore out a brand new RRC, so what have any members here done with their RRC's and oversized TB's.
Im thinking of maybe having it custom made 64---->66.5

Thanks for your help in advance.
