Hello, my engine builder wants to get my motor finished which means I need to buy an oil pump. I have researched the topic, and have come to the conclusion that the Tomei is the best, followed by the HKS, JUN, and then the NISMO pump. I hear alot of negative comments about the N1 pump, although the comments are usually not followed by actuall experiences. The car will only be used for occasional drag runs and messing about on the highway. I would like to see the engine produce around 600 whp without excessive revs (8000 rpm max). My question to you all is, can an N1 pump handle the these conditions or will the next step be necessary? The engine is fully built, forged pistons, rods, ARP bolts, balanced, ported/polished, springs, esc. I would truly appreciate the advice.
