100 shot of wet nitrous. ( a full put together kit from a very good brand name )
3.73 gears if auto 4.10's with 5 speed
Set of long tubes
Wind star intake swap
Fuel system upgrade ( probably just injectors but I don't know the 94-98 fuel pump )
Once all of this is on the car, have it dyno tuned. Should be good for a 100 hp increase at the wheels
If you have extra money, throw a stall in it if its an auto or a better clutch if its a manual.
I'm with rob done with engine gonna upgrade the lower and then either something diff like m90 swap,4.2 or swap ur heads and upper and lower intake from a 99 and get split port u need more thoe nrver done it
