Here is a picture of the oil injection lines.
Could be aluminum. There is that $1200 stepper motor
apex lube oil injector pump.
AKA apex lube oil metering device.
You could off set the cost of your RX8 motor by taking this
off and selling it.

Could also be that the lines are just steel for the show engine, as they may not have yet tooled up to make the formed nylon ones. Notice that there are rubber hose connections, these are not likely to make it to production. I think Mazda likes the nylon because you can see if the oil is flowing.

I sure hope thay are not that dumb.
Come on Jon look on the bright side :-) The nylon lines have rubber jackets
too. Damps vibration.
