Hey Mike, I'm sure the NSW blokes will chime in re what and where you can run it in, but I'm going to leave you with just one suggestion, when you "overhaul" the car for track use, dry sump it. The up front expense will more that pay for itself financially, not to mention how much more relaxing going racing is when you don't need to worry about the things dumping their guts everywhere.
And yes, get it to Superlap!
