Hey Sean... cars looking good. You'll have to let us know how it goes/handles with that setup.
Also be interested to hear how you get on with Rego, if they cause you any grief without an Engineers Cert or not.
Interesting thing with mine Engineers Report.... I spoke to the enggineer long before I did anything to the car and he said he'd pass it with the a15 in it, and RTA said the same thing but any change in engine size RTA definately wanted Engineers Report.
When I finally got the Report from the Engineer, he's listed the motor as a15, which it is, but mines running 1608cc so he obviously didn't give a stuff as to the capacity, just as long as the original engine was within guidelines. You could take the L16 out to 1800cc and would they care..?? No-one has asked for a final capacity measure on the engine.
Another interesting thing, he told me what the engine came from and the year of the donor vehicle just from the engine number....and he was right. He had a book some 6 inches thick which listed everything.
