The stock regulator should be just fine assuming that you are running the stock injectors & rail. If you feel like purchasing a adjustable FPR Aeromotive has a good selection. The rails are different between the Turbo II & NA which model do you have? The NA rail the FPR is bolt on by 2 bolts. You could have some one make you an adapter, you could have someone drill & tap the stock rail for a fuel fitting or banjo bolt. Then there is always the choice of buying an aftermarket rail with provisions for an aftermarket FPR.
You can buy an adapter like this from HKS, SARD or Treadstone:

The Turbo II rail is set up differently, if I remember right the regulator is welded on.

Well there's a few different styles. The one above has a male AN fitting, some have a barbed nipple & some have a female end. You can Google Fuel pressure adapter, but I will give you one link.

The turbo rails would have to be modified or run aftermarket rails.
