I would also like to find out this information.

When I replaced mine with the Walbro pump included in the JRSC kit, the OE pump was twice bigger.

The VTEC's supposed to be good up to 300 crank HP, i believe.

from a post in the FI section by doug at hondata... this doesn't directly tell you the LPH rating, which varies by pressure anyway, but it does give you an idea of how much fuel the pump can flow. the trick is, if you want to push 300 crank hp with the stock pump, you need to be running 440-550cc injectors. to get that kind of power on stock injectors would mean crazy fuel pressure, and the stock pump drops off like mad as the pressure goes up.

it appears to be the same as the Si, which Helms '94 says is 205 cc/10 seconds, or 20.5 cc/sec. LPH is liters per hour, right? If so, then LPH is 73.8 ... does that sound at all right? Well, whatever, the first sentence is correct, I'm sure of that
