fuel pressure regulator

I'm in the process of converting to single turbo. I will have 850cc primaries ,1200cc secondaries and a walbro fuel pump for fuel. My question is will the SARD fuel pressure regulator and stock fuel rail work for this set up? I have the a-spec gt3574 turbo kit in mind.

Thanks.

I have no idea, Darkside. It depends on the input to the SARD -- is it in NPT or AN? Either way, it's an issue of using the correct adaptor to plumb the regulator.

will the stock fuel rail with the injectors I described be enough for the single turbo system, or will I need to replace the fuel rail and use a different type fuel pressure regulator?

thanks

yes the milled primary rail will work just fine. I am currently running a similar setup. I'll see if i can get some pix up for you today.

I don't have a good pic butI'll describe my setup.

Fuel enters the rear of milled primary rail, then exits the front of the rail and connects to the front of the secondary rail (rx7store rail with 1600cc) using the stock banjo bolt. The fuel then exits the rear of the secondry rail and loops forward to the sard FPR using braided lines and AN fitting. then from the FPR the fuel goes backto the stock hard return line. AlsoI have a gauge hooked up to the FPR. I'll have to dig around for some old pixof my install. I probablywon't be taking of my UIM anytime soon.

hope this helps
