Yes, they fit. The B20 is the same as the Ls block, but with a bigger bore. You're going to want to use the LS crank pulley in order to keep the factory power steering and such. I don't remember all the things needed to do for the swap, though.

yes, you'll need to re-use the LS intake manifold.
also, since a super high percentage of b20s were mated to an automatic transmission, you'll have to take out the flexplate/torque converter and put your LS flywheel on there.
if you keep the LS ecu bone stock with the b20, your mileage will suffer as well.

its just the way it works out. rich or lean, its still a mismatched ecu/engine pair.

In the odd chance that this swap would happen on a California car, you should be aware that the B20 swap is de facto illegal.
The CRV is in a different EPA class than the Integra, so even if you get a 99-up motor and swap all the emissions equipment over, you will fail the state BAR referee test.

Replacement Engines
Entire engines can be replacement parts. As with any other replacement part, the engine must be identical to the original. If the replacement block or engine is obtained without emissions equipment, all the equipment from the original engine must be installed on the replacement block. If the engine is not identical to the original then it is not a replacement part, instead it is considered an engine change. Engine changes are a modification that must meet certain requirements to be legal (please see "Engine Changes").
Japanese Replacement Engines
Used engines imported from Japan can be used as replacement engines as long as the engine being used has been identified as functionally identical to the original engine. Please refer to the engine importers catalogue to determine if a replacement engine is legal for installation in your vehicle.
Engine Changes
Engine changes are legal as long as the following requirements are met to ensure that the change does not increase pollution from the vehicle:

- The engine must be the same year or newer than the vehicle.
- The engine must be from the same type of vehicle (passenger car, light-duty truck, heavy-duty truck, etc.) based on gross vehicle weight.
- If the vehicle is a California certified vehicle then the engine must also be a California certified engine.
- All emissions control equipment must remain on the installed engine.

A B20x with B18b intake and exhaust manifolds is just an overbored B18b, under normal operation the O2 sensor will account for any rich/lean conditions, and I doubt WOT will be dangerously rich or lean. People run far worse combos than this all the time.:shrug:
