    Ive got a 338 sbf, 88mm t6 turbo, a/w intercooler. Im leaning towards a tial 60mm, is this too big, or could I go with something a little smaller? I'll be running around 25psi. Thanks, Eddie.

    depending how low a boost pressure you want to run you could use a smaller gate but if you use a 60mm you'll never buy another one again and run extremely low boost if desired. It's like a fuel system......bigger is better

    +1 on the 60mm... x02 has decent wastegates at a much cheaper price than the Tial stuff...

    Another option is to run 2 smaller wastegates. That way if one sticks for some reason the other one may save your engine. That is what I did, 2-38mm gates instead of 1-46mm. It was Brian@B&G TURBO's recommendation when he built my kit.
