Ok so i've got a few questions before I make this swap final. To start off with, I want to buy this engine http://www.hmotorsonline.com/shop/sc2000search.cgi?what=page&item=30009 and install it into my 2000 Honda civic automatic. This particular engine comes with - Motor - Hydraulic Tranny (S80, Y80) - ECU (P72) - Axles with Half Shaft - Shift Linkage - Stock Motor Mounts * - Alternator - Starter - Clutch - Flywheel - Intake Manifold - Exhaust Manifold - Fuel Rail - Injectors - Distributor - Engine Harness - Comes With All Sensors Needed Now my main question is, since a 2000 honda civic ex is OBD2b, and since this engine comes with a P72 ecu and engine harness, will this engine basically just bolt up/wire right into my civic with little hassle, or will I have to do some modifying to the engine wiring harness? And my other question is.. The hm motors website says that this engine comes with axles and half shaft, does that mean that I won't have to buy any other suspension related parts like this? And if your still reading at this point, my last question is.. Even though hm motors website says that this engine comes with the stock motor mounts, will I have to buy any extra mounts for the engine? Sorry if this is all hard to understand, i'm just really tired as I type this. And any answers would be sooooo helpful that I cant even explain.
