you would need si trany which will have to be the 5sp. cuz I don't think the integra ls trany would fit and your "D" series motor trany would not fit for sure. You will also need axles, engine mounts, ecu, wire harness. It is a full eng. swap. You can not drop in the b16a2 with out upgrading everything else. Because you are going from a "D" series motor to a "B" so everithin is different. Good luck. Stefan525
