Shawn - welcome to the club, and I think your move over to Australia is a wise one !
You might want to send an email to Richard Bendell via his company's general email address
admin@motec.com.au Richard played a part in the design and construction of a Daytona Coupe over here. Peter Brock (the original Daytona designer) mentioned how nicely in proportion the car looked relative to other replicas.
Richard plays a significant role in the running of Motec Engine Management Systems - one of the most highly regarded racing datalogging and engine management companies in the world. As such, his budget might not be what others consider a "budget", but it's worth an email.
No doubt you would have seen the online videos of a guy named Darius with the supercharged LT1 powered Datsun ? Great stuff ! Do you really need a V8 240Z, or would you be just as happy with an RB26 powered, twin turbo monster? There are a couple of them getting around here these days, and they're VERY quick....
