I'd recommend that you ask this question in the FI/Nitrous site. Lots of folks in that section have either done the conversion or has researched it. There are even some aftermarket upgrades that seem pretty straightforward as well.

Good luck, I may be doing the same thing in the near future.

I believe you need to basically swap out the tanks with a pre ffs fuel system, put in the hard return line, filter swap, and rail...

What is so great about a '97-'98 fuel system that would make a person go through all that work to convert it?????

The later year fuel system wont support HIGH hp applications. The older 97-98 "Return Style"( It helps maintain higher fuel pressure) is the best system avail for this situation. That is of course until you go with an entirely new aftermarket setup like ECS or APS fuel systems.
