whats your budget ??? then you can narrow options. ls vtec motors are great under 8k rpms unless you build the bottom end to hold higher.. but there is some things to do first..
since your car is a 91 and if its still stock its odb0 ..you need to buy a jumper harness for vtec ecu, engine, and dizzy. for it to run proper.. you can use some short cuts but you get what you pay for lol ...
if you want a turbo motor just build your ls and boost...
