well psc has some pistons and rods, but i think thats about all, the only other ones you can get are probably going to have to be from america, as with the other parts
apart from that you can try rpw, they have camshafts and accessories, flywheels and other various parts for some hyundai models which i think includes the beta model engines,
the websites are
www.rpw.com.au and www.performancestylingcentre.com.au
Goto www.kspec.com They have lots of performance parts for the beta and betaII. If you dont see what you are looking for then go onto there forums and ask for what you want and he should be able to get or help search for what you are looking for. Good luck! I plan on going turbo this spring on my betaII and getting some other toys from kspec.:
