What would I have to do to swap a CRV engine into a 90 Integra. From what I know that the B20B is the samething as the LS block out of my car. The Crank is the same but the bore size is different- 81 vs. 84. So my guess would to swap the intake manifold so the wiring matches. But what about the OBD0 to OBD2? Please help. PS and I dont have enough money to get a K.
