Hi, can anyone tell me at what stage of tune should you uprate the oil pump on a cosworth, it had a full rebuild to a standard stage one, 3 years ago and has done little mileage since then but since then I have gone to a stage 2 about 300 to 320ish BHP,
so I was wondering if it is worth uprating the pump, as I will be taking the sump of this weekend to fix an oil leak anyway. Cheers!
