You could also invest in some sort of fuel controlling device, but Im not sure about the SAFC as I remember somthing about it screwing with the timing, someone help me out here. Is this a serious post, Injen, haven't you been on this forumn for a while?
You guys are making my head hurt. Stock FP on a 96+ is 52psi. The FPR is NOT vacuum referenced so you are running 52psi all the time. It's true that if you were jetted high enough on the fuel side that it could potentially cause a pressure drop in the rail but that's highly unlikely on a 100 shot. If you want to caution on the side of error then get it. You might be ok with just a fuel pump rewire mod.

I hear about more people melting valves then i do pistons. But with the combination of forged bottom end and the ss valves you should be able to pull off a 150 shot.
i was thinking ss valves would be needed. anything else for the head? i will probably put some nitrous grind cams as well as some cam gears in there later on but is there anything that would insure the engine was capable of handling a 100 to 150 shot? thanks for the input btw.
SS valves are a good investment ... it'll prevent you from toasting your valves. If you get cams definitely get some cam gears to fine tune your timing. With the cams may come some idle issues because of less vacuum but that really depends on how aggressive the cam profile is. I don't know if the stage 1 clutch will hold 150 but I'm sure it'll be fine holding 75-100. Obviously just don't spray right when you dump the clutch. Get rolling first.
