I've used the complete Galaxy engine, the cil head is skimmed down for higher c/r, mine's 1:10.8, ported and gasflowed, piper ultimate road cams,
inlet plenum and exhaust manifold from RS2000 engine, original ECU with custom programmed chip from Motorsport Developments and small turbo Escort cossie fuelpressure regulator, mines around 185bhp and 185lb/ft, a mate of mine has owned many RS turbo's and at the moment he's restoring a RS1600i at the moment and he says if i ever built a track car this engine is coming in because it's so powerful with the loads of torque it has at the moment
