Civic-Integra

I have a 92 Honda Civic CX, and a 91 Acura Integra GS. I belive the bottom end in the Integra is blown. Can I swap the bottom end from the Civic, and still have compairable preformance?
If not what would be a good engine swap, for an afordable price?
What engines do I have? (b15 or b16 or what?)
