Temujin said:i've been told nissans esp silvia's n skylines haf this prob, bad oil pump. perhaps u need to change to n aftermarket oil pump.
i currently dun haf that prob tho..
unfortunately there is no aftermarket upgrade for SR20 Oil Pump... i don have that problem even with Oil Cooler add on also... perhaps ur using wrong engine oil vicosity OR.. ur Oil Pump is not in good condition already... suggest that u replace it with NEW Oil Pump instead...
