recommended fuel pressure

[Tribal_RS_96]

I got a adjustable fuel pressure regulator from eBay. I was wondering what the factory fuel pressure is. Thanks. I'm also still on the stock rail and injectors.

If the rest of your fuel system is completely stock, there is really no reason that you would need an adjustable fuel pressure regulator. Keep the stock regulator on there.

Jared is correct. Unfortunately, we see these 4G63 guys posting up when they just don't have the correct information

I wish I had a stock one, when I bought my car half assembled, there wasn't a factory FPR installed. Im swapping a new motor in and I want to make sure I'm running all the factory specs.
