I would not recommend getting engineering reports done interstate if coming back to sa. I had my previous car, series 3 bluebird with a CA18DET dropped in it, engineered in nsw because i moved there for 12 months, then tried to come back to sa, and they would not except it. Wanted it engineered again here, because our laws are more stringent or some shit. End result, spat the dummy and bought a 32, because i refused to pay another $1200-$1500 to have it engineered, when it only cost me $300 in Wagga to get done.
