Does anyone know of a higher volume oil pump to replace a stock LS pump?

OIL pump...not Fuel pump.

You can install one from a Type-R. Yes, it fits even though it is designated for a VTEC block.

 

Any vtec oil pump would do. If I'm not mistaken, I remember reading some where that 98+ LS and B20 blocks use vtec oil pumps or at least the part numbers suggest so. I'll see if I can find the original post.

 

sorrule, you don't need to find the thread, bro. I have installed Type R oil pumps onto LS blocks before and it works without a problem. Those oil pumps can be purchased brand new for under $90 or so from an Acura dealership (online of course).

 

Ls, GSR, and Type R, Civic SI, del sol VTEC, etc.. use the same oil pump.
The pressure is controlled from the main/rod bearings.

Look up the part numbers www.hondaautomotiveparts.com
Yes, you can use any B series oil pump on any B series block, minus the old b20a or whatever the old prelude engine was.
