Chassis: 1991 Acura Integra LS

Question: Which swap would be ideal for this chassis? B16 or B20?

More Info(Will update as needed):
This motor would be an all motor setup. With the possiblity of going boost after switching back to a lower compression pistons.

I just wanted to know what everyone thinks. Again I didnt say anything about any other motor. The Poll is reguarding these two motors.
