Stock for a 93 is 205hp, 260tq. With the pulley, intake, and exhaust, count on 230-235hp. The intake and exhaust only support the pulley change, and don't add much by themselves.
Remember that even though you would be approaching the Series 2 hp/tq spec, your peak delivery is at a much lower rpm. The S2 would out-distance you on the top end.
If you don't have a scantool or fuel pressure gauge, a 2.3" pulley would be the safest smaller size to go to. If your fuel pressure is good (at least factory spec) and you have a scantool to scan for KR, go for the 2.2" pulley. But be advised that if you get KR with the 2.2", you'll have more work to do ($$$).
