where to buy turbo manifold for internal wastegate T25?
#46
Or you can switch to a 4-bolt MHI outlet if you wish, and then use a segregated wastegate recirc down pipe, which would help with boost creep through smoother flow and less back pressure.
Which would make your whole setup more efficient at the same boost, which is a good thing on pump gas.. especially if 91 octane is your only premium option, like in many parts of the country
