#271951 A New oem Honda stock b series vtec oil pump will take most anything you can throw at it , the only oil pump problem I've heard of is stroker engines 90mm+ stroke breaking oil pump gears and that's because of increased harmonics . If in doubt Unorthodox racing makes bullet oil pump gears you can invest in them

#272176 Exactly how high do you plan on revving the engine? Will it hold those RPM's for an extended period of time?

If you're building a road race engine, then you might wanna look into a Accusump oiling system (or something like it)

Never heard of Unorthodox making such a part... I just browsed their site and theres nothing on it about oil pump gears. I know Endyn modifies OEM pumps to hanlde the abuse he's talking about and Prodrive make/made gears for B series pumps.
