RB25DE,
takes approx 5 ltrs of oil, filter is a Z145A and there is a smaller option but the bigger the filter the more filtration = GOOD
Other than that if u drive the car hard use reasonably good quality oil and change it every 5000k's. I flogged my car everywhere and the oil was black after 5000, internally the engine looked like new though. I used Magnatec which was recomended using nething better is not necessary. ummm dont know much else on the engine it self.
check water ever servicee it generally wont go down unless u have a leak though
Power steering change every 40-50000, just use a good quality auto tranny fluid.
Not sure what else, i cant remember pad numbers for it but im sure if u search they will still be on here.
Plugs i wil check soon,
Fuel filter i will also check
Air Filter: use k n n panel same as for the turbo option for your model.
