To do the same setup i have done with this turbo is not a costly exercise.. Turbo cost me around 1800 then delivery, manifold was 250 then hadto modify it to be perfect, gate was 570.. You could use cheaper parts, but i dont want to stuff around fixing things twice, so i went braided everything and made another wastegate outlet with a screamer, full 3" exhaust, 4" intake pipe, Put the elbow on because if i was to put a silicone bend it would melt.
So realisticly the figures to set up everything would be roughly 3,700 or so doing it right.
