hi, ive got at sierra cos 4x4 final edt. it drives stage 1 with a mongoose,cone,pace RS500,2wd flywheel.1,1bar and std injektores. and a stainless ekshaust manifold, when i changed the manifold the pressur raised abaut 0,2-0,3bar. and the cars are a LOT more responsive (std T3 4x4 turbo)

my new plan are a costum intel manifold with the standart trottleboddy, i know my spec are overkill, BUT then the question. do people have any xperience if the car gets more responsive wen you change the std inletmanifold to a other model?

my aim are 300 hp and a wery revy engine. ita okay fast now. but just want 300 real hp.

there are ofcurse coming a GT28 or GT30 turbo on and wastedspark and some 440ml injektores + costum chip.

just need to hear abaut your experience on manifolds.
