Oh, mate is doing a track car so legalities doesn't worry him.
No idea about QLD but not legal in VIC unless it comes from factory (think late model N12 Pulsar ET).
BTW, when you're shopping for turbo on the GT-V, make sure you get low mount kit not high mount kit. Mate and I discovered that top bit of intake runners hitting the turbo.
Don't pull the engine apart. Slap a turbo on it, drive around til it blows then buy turbo motor or RB30. A mate is doing 25de neo + Trust T67-25g on his (work in progress).
Yah, was shown what a failed balancer can do...
When old one wears out. I thought about getting Ross/ATI but was told not to bother for stock motor and ended up getting another stock balancer when mine worn out many moons ago.
Plus reading few stories about Ross balancer throwing ancillary belts 'cause it was out of alignment to stock ancillary pulleys.
