If you plan on going E85 then I'd be throwing in some id1000's and a bigger fuel pump but if you want to stick to 98 then the standard stuff should be fine. You should be able to make a bit over 300rwkw on 98.
I have all the basics and am making 325rwkw. Power FC, E85, id1000's, walbro 400, -7's, 3" exhaust.
