ive had this conversion b4 on my first rst done by jano at oddkidd creations, i would say management first, smoother running, mutch more reliable than shitty mfi, very noticable power increase, my car was running standard t3 with -31, standard bottom end, standard head cam, car produced 212 bhp, and engine wnt on for 20k, no issiues but put a low comp bottom end in that came up cheap, the engine is now in my combi van,
