well thats it as im only on a stage3 t3 at the mo but it will be pumping out around 25psi and then i was either a t34 on my manifold or save up and get a big manifold and gt28 or something like that. so i think i will kill a cts box .

whats the 6 speed st170 box like for ratios ect compaired to the mtx75.....
