I just bought a 91 CRX HF and the motor threw a timing belt so Im betting the valves are bent, My friend has a motor out of a DX, its a dual point motor. My question is, can I just put the intake off of the Hf on the Dx motor? or do I need to swap over all of the sensors?

 

If the motor is from an obd1 dx then you need to bring all the sensors from your motor over and swap the manifold.
