R33 GTS-T - Timing belt or Chain?

[speedmachine]

Ok you can probably see by my posts that I don't know much about the R33 GTS-T

Does it have a timing belt or chain?
All my previos cars have had a chain so is there anything I need to know about the timing belt? How often should it get changed and how much woudl I be looking at to change the belt and pulleys on an R33 GTS-T?

Thanks!
