Well I plan to build something similar this fall/winter, but I am using a DE 53j block sr16 pistons, eagles H-beam rods, ACL ace bearings, cosworth studs, VET head gasket, s4 or c2 cams, bc s/r's, jwt cam gears if needed, charles 4 to 1 header, 3" exhaust, a direct port 150 shot of nitrous, caulm r/t ecu tuned for the above. I am expecting well over 300whp and more torque on the spray and probably about 220whp off the spray, so it should be a pretty leathal set-up. I still have to find a shell for it, maybe a b13 if I can find a clean enough one........
anyway we will see.
Goodluck with your build and your going to need nitrous or boost to achieve the numbers you want.
