Basically you can squeeze some more out of it.
I added Genie extractors with a V8 Crudadore catalytic converter running through a 2.25" exhaust with a high flow muffler.
I had the car dyno tuned very soon after and they tinkered around with some of the EFI settings. Power went from 76Kw to 93Kw at the rear wheels. Mine already ran a snorkel with Finer Filter (foam) and Magnecore 8.5mm (KV85) ignition leads. It was a very noticeable improvement.
You can get a chip for the ECU (various aftermarket suppliers) and a 60mm throttle body (standard is 54mm) from RPW -
www.rpw.com.au in WA. But I think they will only yield higher rpm power the 3.0 V6 needs more low down torque.
I guess major work would involve raising the CR and cam regrind to give it more mid range grunt. The other option would be a supercharger but thats $$$ unless you can buy a 2nd hand unit off Ebay and do a lot of the work yourself.
