Seeing as you have a 90 sc, we have the crappy exhaust with no chance of duals. Get some nice 2.25 inch downtubes made going into a dual in 2.5" resonator, 3" out that then slits out into dual 2.5" again going into your mufflers of choice.
Now that your exhaust is covered, throw in an upgraded fuel pump (190lph for $83, or 255 for $90). Next, an upgraded MAF. ($30 from 91+, $110 for 73mm, or $140 for 76mm). After that, throttle body (prolly just a 70mm). Finish off the intake with a zr or mac cai for around $170.
Now that the intake, exhaust, and fuel pump is done, throw on a 10% sc overdrive pulley for $60, then a raised sc top ($200) and intercooler fan ($60). Underdrive pulleys are next at $150.
You should easily be at 300hp by now at the crank, but if you want to keep going, get a 180 degree tstat ($6), larger injectors (38#'s for $290), port/polish heads ($400), a jerry chip/tune, and maybe some headers.
If ya really want to get frisky, send off your blower to get it ported
