That's not the best swap to be dropping into a 94 EX. You're talking OBD0 electronics and a cable tranny into a hydro equipped OBD1 car. If you're set on the swap then you're going to need the HASport hydro to cable conversion kit and mounts, then change the distributor, injectors and ECU to OBD1 parts at the very least.

For shift linkage you'll need a 94-01 Integra or 99-00 Civic Si linkage. Axles can be 90-93 Integra axles and intermediate shaft or 94-01 Integra/99-00 Si axles and intermediate shaft. If you go with the later of the 2 then you'll need to change the passenger side tranny seal to a 94-01 Integra seal.

I'm pretty sure he is going to use a newer hydro trans, just using the LS shortblock primarily, with a newer b16a hydro trans (i believe that is what he is going to use for the tranny selection). That should simplify most things correct?
