Welcome to the Forum,

The G-Force is probably your best option living in WA. It'll be nice to deal with a local manufacturer and the new G-Force body looks excellent.

Think carefully about your engine choice before shelling out the $$$. My advice would be to buy the kit first and the engine later. That way if the emissions laws change you aren't stuck with a non compliant motor.

Make sure you pass your idea by an engineer before buying too. The 302 may not be emissions legal in your state and LPG might be a problem too. It is in the other states any way.

The advantage of the supra box is it's cheap but I reckon you would be better off with the T5 behind the 302. It's a much simpler and tidier installation with no need for custom bell housings etc.

Have a talk to "Plums" on this forum. He's in Perth and has just bought a G-Force kit.

Cheers
