I spoke with George at TTi the other day about the 66mm exhaust housings, and he said he can't get the 0.82 exhaust housings from Turbonetics to be machined to work on the new Precision unit. The Corvette kit is likely stuck with the 65s indefinitely. I don't think TTi has plans of redoing their kit since it was designed around the 5-bolt exhaust housing to consolidate with the smaller sized turbo kits.

62/65's are plenty for a street car anyway
