Spa turbo is in Brazil the corsa gsi manifold has the same 9bolt pattern as our ecotecs. The flange is for a T2 small(lol) but T25/t28s sbould bolt up as well. Its priced @$246.25+ shipping( USD). I beleive its possible to build a good turbo street car for a $ 1000-1200 including a Trifecta tune(pickles says so) some used parts n a junkyard find turbo for even less.
