    If you have a 6NZ set at 600, it has been turned up, and thus, who knows what turbo it has on it... especially if the injectors have been upgraded as well. There MIGHT be a little tin tag on the engine side of the center cartridge of the turbo, between the oil supply line and the manifold mount boss. It's nearly impossible to get your head in there to read it, but a cell phone can usually get a readable pic.
