Specifications:
Design: Intank
Flow: 160LPH
Minimum Voltage: 12V
Max Operating Pressure: 95 PSI
Part Number: SPPG-392

It is the same part for:

1986-1989 Acura Integra
1990-1992 Daihatsu Rocky
1984-1985 Mazda RX-7

I hope this helps you !

Mazda specifications for fuel pump and stock injectors.
Outlet pressure 350~500 kPa (49.8~71.1lb/in2)
Pressure reg no vac at control solinoid 260kPa - 36.97psi
vac at 200kPa - 28.44psi
injector volume 173+/-24cc/15sec.
Don't know if that might help someone figure it out.

Mazda doesn't give a fuel pump volume spec for the EFI cars as it does for carb models.

I never checked what an unrestricted pump puts out on the se, Do know that it really makes one hell of a mess if you do forget to hook it back up.

Since Mazda no longer sells the pump for the GSLSE the walpro seems to work alright on a flow ported motor and intake which passes IM240. Still working on my se although it does make some noise once and a while.
