I have a 98 LS motor that is being completly rebuilt and I need an opinion on my stock oil pump. I am aiming for the 350+ HP range so will the stock pump be good enough? The clearances are on the worn side, so I would like to at least replace the rotors and relief spring. However, I can't seem to find this offered from Honda. Other option is to buy a new OEM pump for $100. Does Honda offer the rebuild kit? If not stock/or aftermarket pump?

 

Just buy a new OEM pump. We all use them for much higher HP goals than that.

 

So does that mean the do not offer the replacement rotors to rebuild my old pump?

 

I don't think so, everyone I know just buys a complete oil pump.

 

you can use one out of a gsr. but you'll need a gsr timing belt then too.
or that might be the water pump, but im pretty sure its the oil pump
