Tomei or N1 Oil Pump?

HI I have established that my original 92 rb26dett oil pump cant keep up. I will get up there in the RPM range (5k-6k) and i suddenly lose all oil pressure. Dropped to 0 on me at 6K.  Im now looking into the tomei or N1 r34 oil pump.  Or even a electric external pump. What do you think will be my best bet. Thanks.

Are you sure its the pump failing or are you emptying the sump? Try over filling by one litre and see if it makes any difference.

Tomei is the best pump although N1 pump should do it. A few years ago there was a string of N1 failures although some people put that down to a batch of knock offs.

Since you will have to pull the engine to change the pump you may as well use the opportunity to fit some oil restrictors. Have a read of the last half or third of this thread:
