It's a really easy swap if you the whole changeover. But if you get a longblock make sure it comes with the manifolds (some peoples idea of a longblock is different). you will need the wiring harness and ECU as well. Other than that it's easy as pie. also don't forget the spring pin ($3-4) and clamp($1-2) for the shift linkage, the O rings for the exhaust manifold ($10.00) and cat ($18.00). A valve cover gasket ($6-7), timing belt ($30.00), water pump ($45.00), exhaust manifold gasket ($15.00), and check the clutch on the new motor too because it's a lot easier to change when the motor is out. How many miles are on the D16Z6? I would also get a new oil seal for the distributor if you are going to take it off before lowering the motor in (you can leave it in but if you damage it when putting the negine in you'll be sorry because it's expensive-$300.00). And you might want to check your motor mounts because if they are shot you will need new ones (about $200.00 for all of them). And yes the drivers side mount is different, you will need the mount off of the D16Z6 (both the part that bolts to the block and the mount that bolts to frame of the car) I will let you know if I think of anything else.
