my friend is building a monster h22 on boost hatch and is in need of a perferably topmount manifold that retains a/c. the catch is also that he has a t4 turbo. hese called fullrace, revhard and i dont know how many others he told me. the closest he has gotten is having them tell him, if you switch to a t3/t4 we can make it happen. does anyone know who might be able to build him one for his combination? a ram horn would also be acceptable at this point.
