I have a N1 Nissan Genuine Pump now and restrictor in the galleries to the head so considering the primary usage of the motor to be street so sustained High rpm will not be a REALISTIC option. (Training to be a cop so High Range Speed Fine and HOONING would not look good). Running ACL Race Bearings so with good maintenence I am imagining it will be fine.
If I go drag racing or circuit I am going to run an oil cooler and a litre extra oil as safety because that is how the guys on here tend to manage it. I have oil pressure and temp gauges now too!
