Hello, I gotta 2000 EK with a B16A3 motor converted to OBD2. I'm still running a stock DX fuel pump, but I have a chance to buy an SI pump with 25,000 miles. Does anyone know how much lph the SI fuel pump shoots out? Because I'm not sure wheater to buy this pump for dirt cheap or buy a 190 LPH Walbro. I'm going to be using a dry NOS system. I know those are designed to be used with stock fuel systems. I'm running ITR injectors and a P73 to make the motor run just a bit richer. Also have ITR flywheel & header, GSR tranny, RS*R exhaust, Magnaflow cat, Injen intake, Excedy clutch. My main concern is, will the SI fuel pump be adaquete enough for the 50 shot of NOS? I know as long as there is enough fuel, nothing can go wrong, plus my motor is very healthy. So, SI pump? or is a GSR one better? Or just get a Walbro?(which is really my last chocie because I don't wanna get a fuel pressure regulator, I want a simple setup)

yes the dx fuel pump is enough. i ran a 75 shot on a 4dr dx auto for a year with no problems what so ever.

But were you swapped?

Go with a walbro. You can get them for like 80 bucks and they are worth it. the stock d series pumps are 97lph. and bseries i beleive are 134lph.
