1993 - Adjustable Fuel Pressure Regulater Needed

I know that the 1993 fuel rails are different from other years, so is there an adjustable fuel pressure regulator that will work on it?
I currently have a 52 t/b and a set of 30 lbs injectors that I will be installing when I finish rebuilding my motor.

Thanks

Why do you want to adjust the fuel pressure?

As Fred said, why? You shouldn't need to make any pressure adjustements. Forced induction is a different story, but for NA, a stock one will work fine.

Even forced induction it's not necessary. Factory fpr raises 1:1. Unless you're trying to offset not having enough pump.

I wouldn't touch fuel pressure

With those mods you don't need a different fuel pressure regulater. Stock will work.
I have a 93 too.
Fastbird had a 93 and is very knowledgeable about our years.

Good to know... just saves me some cash for other parts.

I had to adjust mine. :D Granted, I was running BIG low impedance injectors, and had trouble with getting a clean idle to the point of backing pressure down AND pulling the BPW down from 1.0 to 0.8 milliseconds. But you're exactly right. The factory regulator is a 1:1 pressure rise (as is on the return style railed LS stuff too, I was running a factory rail/regulator on my Vette and may move back to that even) and unless it's a situation where the injectors are simply too large to control adequately via tuning, you should NOT have to touch it.

Unless you are a cool kid with enough pump to run high rail pressure like LSX kids.
