Skylines Australia - Queensland
Ended up buying some screw extractors. I don't know if that's what an 'easy-out' is, but they didn't work at all. I ended up snapping one, but luckily managed to get it out of the hole I'd drilled. After getting fed up with trying to get the 2 snapped bolts out, I made a few calls and ended up taking the turbo to Edsway Engineering over at Coopers Plains.
I can't speak highly enough of the guy that works there. Not only was he on holidays and came in just for me, but it only cost me $20 to extract the 2 bolts out and re-thread the holes. The addy is 20/248 Musgrave Rd, Coopers Plains for anyone interested. And is it just me or is it friggin hard to bolt the oil and coolant lines back to the turbo? I must have spent at least an hour trying to line everything up.
