does anyone know were i can find an adjustable regulator to fit a 93 sc2 and about how much should it cost.thanks

Its located on the right hand side of your fuel rail. They were adjustable in the earlier DOHC S-Series. Now the real question is, are you wanting to increase or decrease fuel pressure?

i am working on a motor for my 93 sc, it will have a lightly ported head, an extrusion honed intake, a header and flowmaster muffler. from all of the info i have read so far after i have it together it will be getting alot of air and not enough fuel on top end. i would like to have the ability to add or decrease fuel as needed for my motor.my friend has a sniffer that can tell me my air fuel ratio so i figure i can adjust it from there. maybe you have some more input for me. thanks steve

These engines run extremely rich in stock form. People with stock engines, lightly modified engines and even highly modified engines with the exception of a turbo or superchargers have found the turning down the fuel pressure gets good results.

thanks mike thats good to know, can you tell me what year regulator to look for and if it will bolt directly on my 93 fuel rail. i also have a 92 fuel rail but they dont have adjustable regulators. thanks steve
