a good clutch is around $900-$1300 for a southbend, plus a fueling plate is $150. and with a 215hp pump ('96-'98 manuals) you can make excellent power for the cheapest money. i believe a #0 plate with stock injectors will yeild around 360hp, correct me if i'm wrong. so add some bigger injectors (~ $400-$800+) and a 16cm turbo housing. straight piped exhaust is cheap unless you get a 4" or 5". especially with that pump, you'd be doing great on power for cheap moola
if you want the auto, well, prepare spending $3000+ for a good, reliable (not just converter and valve body) transmission. but then that extra $500 left over can make 300hp or so. just depends on what you want, but that's a decent outline.
