hello i have a 97 integra obd2 and the motor went so will a b18 out of a da integra work with my car or no i was told i will have to use my knock sensor along with my intake and fuel injectors along with fuel rail. also is there any other engines compatible with my car without having to do the engine harness and ecu swap and stuff like that just plugand play

 

Reuse your distributor, alternator and injectors. Intake manifold swap as well. Neither engine uses a knock sensor unless your car is a GSR. Also you'll need to wire the fan switch to the back of the block. You'll need to do the CKF bypass, search for that on goggle and you'll see how. Honestly though in most states it illegal emissions wise to swap older engines into newer cars.
