Are you saying youre replacing a B7 with a Y7 or putting a B7 into a 96 civic? For the Y7 to go in the 92-95 yes use the b7's harness, ecu and distributor. All 88-00 D series sohc engines have the same distributor bolt pattern, except the Z6, it is different. Your first post had me under the assumption that you were replacing a Y7 with a B7 into a 96 civic. Trans will not be a issue at all, and use the engine mounts and brackets that go with the car the engine is going in.
