i was just doing some research and have found that the stock exhaust valves on the 16v are 25.5mm.
i have found that trd make or have made in the past oversize valves that are 27.5mm.
the reason i am interested in this is i have heard that bigger exhaust valves on a turbo aplication can make a worthwhile difference.
just wondering what you guys thought an dif you know where i could get some?
