Angry Is there a fuel pump between stock and Walbro???

There has to be some pump that flows more than stock but less than a Walbro! Anyone know of any? Supra? thanks

What about a WRX pump? I also think you can get 190 lph Walbros.

The common Walbro flows 255lph.

Why are you looking for something inbetween, out of curiousity?

To get my fuel pressure down. I know that a pump that flows less than the Walbro but more than the RS will give me plenty enough fuel.

get the normal pressure high flow, not the high pressure high flow which everyone seems to use.

Why don't you just use another regulator? Works for everyone else.

I have one. I finally bought a SVX regulator and still idle at 38psi and build to 85psi at 7# boost even with all the Cartech RRFPR screws at full lean.

Have you set the RRFPR right? Take off the vacuum line and make sure it is idling as low pressure as possible by turning the allen key (with the lock nut) screw... outward? Inward? Well, you'll see it. Just make sure it idles with the vacuum line off as easy as possible.

Actually, if you add it up... 1:1 rise on the normal FPR, 2:1 rise on the RRFPR... idle manifold pressure is near -9psi (guessing since you have that 2.2 with 8:1 compression). 38psi + (16psi * 3) = ~96psi. Kinda near where you're idling now... and if the RRFPR could adjust down just below 2:1, it'd be right on.

If you have that much troubles, try removing the RRFPR from the line, and see what it idles at... bet it's closer to 32psi and that the base adjustment screw is in too far.
