Oil Pump, Water Pump and Underdriven Pulley question

[Bass Junky]

Hey ppls.

My big arse service is coming up in about 10,000 klms, and being the big one, a lot needs to be looked at.

Timing Belt, all fluids etc. etc. etc.

UAS replace the water pump in their biggins service.

Is this nesecary, and is there any real benifit from going to an N1 pump for normal street applicatons, occasional track days.

Same with the oil pump.....

Hi Bass, N1 water pump is designed for sustained high rpm running (as in ciruit races). If you drive it on the street in traffic, with the aircon on, it's exactly what you don't want. An N1 oil pump is the same as a standard RB26 oil pump, except it has a stronger spring in the pressure relief valve. A bit more oil pressure, but no more flow.

Bottom line, spend you money on something worthwhile.
