I am running a GSR engine in a 92 DX civic, gsr ecu obd1 and a FPR.

I am currently on the stock fuel pump and the engine seems stifled. My mega accurate autometer a/f gauge reads a tad rich over stoich at WOT, but I know most people upgrade the fuel pump, which makes sense. My engine's bottom end is not stock... so I know I need one... question is... which...

The GSR pump supposedly is 165lph ? My civic pump is what ? 79lph ? Is it dangerous to run the car like this ?

Walboro pumps are mad expensive where I am... so what are my OEM options that can flow well enough to do me justice...? Some are easier to get for me than others.

Is the civic SiR pump the same as the GSR or ITR pump ?
Is the CRV B20 pump the same also ?
Any other pumps I can use ? Prelude, etc. ?

Also what upgrades would help ? Fuel rail ?

all b series pumps should be the same. around 165 lph, i think. depending on what your goals are for your motor will determine which pump for you to get. anything over 200 hp, i'd recommend a 255 lph pump. check with http://www.lightningmotorsports.com to see if they will ship to where you are located.
