lol yeh pics would be nice, but i really dont think you can get a full cage and the carbon body parts engineered in and way shape or form apart from a dodgy one in nsw, the engine transplant you could get engineered, cover the pod, no atmo bov or atmo catch can, if using external pumps and external surge tank then that needs a fully enclosed box that drains to outside of the vehicle.
If you do only intend on using it as a race car and not driving it on the road, rather than going through all the hassle and might I add extra cost of mucking around with it to get it to an engineering level then paying for all the engineering, blue slip rego etc, just find yourself a car trailer for a good price and then go buy a 90's model v6 auto dunny door with a tow ball, would do the job. You could fit a change of tires and a heap of junk in the back if you bought a wagon.
also can I ask how much you paid for the r33? oh yeh and pics
