I want to run a b20z in a ek, people say it usually runs lean w/ an LS ecu, just wondering if by some coincidence, a new walbro pump would solve the problem... I know about fpr but if the pump add just the right amount of fuel, saves me some money.

So if you have experience w/ any of the walbro models (190/255/255hp) please let me know by how many psi's the fuel pressure increased.

 

94 civic HB (GSR) with a stock regulator and warlboro 190 lph fuel pump. Fuel pressure at idle was 50-55 psi with the vacuum line disconnected. Dunno if this helps any...............

 

hmm, that seems higher than stock right? Anyone know the stock fuel pressure on that car? Is it a dx/cx/vx or Si?

i think 35 psi with the vacuum line disconnected?

 

Ive heard its around 40psi disconnected.. not sure though

 

On my B18C1 w/ stock regulator, it consistently measures 50psi at the fuel filter with the vacuum-reference disconnected.

 

this is w/ the stock pump?

 

Yeah, stock pump.
