Parts List
| Mitsubishi part no. | Part description | Qty | Translation | Why do I need it? |
| - | 2.0L Turbo Cylinder Head (complete) | 1 | 4g63T DOHC head w/ everything inside | Get one cheap; used or rebuilt. Make sure you get the cams too. |
| MD189436 | Gasket, Cylinder Head | 1 | Head gasket from a 4g64 Galant DOHC | Exactly what you need to mate the DOHC head to your 2.4L block. |

| MD182292 | Belt, Valve Timing | 1 | Timing belt from a 4g64 Galant DOHC | Gives you the extra slack you need for DOHC and the extra bit of deck height. |
| MD341013 | Manifold, Inlet | 1 | 4g63T Intake manifold | Our stock manifold doesn't bolt up to the DOHC head. |
| MD192031 | Gasket, Inlet Manifold | 1 | 4g63T Intake manifold gasket | Different manifold, different gasket. Yours is toast anyway. |
| MD307614 | Stay, Inlet Manifold | 1 | 4g63T Intake manifold support. | Bolt hole width (distance apart) on the 4g64 intake manifold is too wide for the 4g63T intake manifold. |
| MD184046 | Gasket, Throttle Body Air Fitting | 1 | Throttle body gasket | Yours is probably fine, but it's a gasket. Replace it! |
| MD195228 | Cable Set, Spark Plug | 1 | 4g63T spark plug wires (Set of 4) | The SOHC plug wires are too deep to fit in the DOHC head. |
| MD184230 | Coil, Ignition | 1 | 4g63T coil pack | The new plug wires have different connectors. Besides the fact that you have no where to mount the stock 4g64 coils on the 4g63T intake. |
| MD322834 | Pipe, Fuel Delivery | 1 | 4g63T Fuel rail | Different mounting bolt locations on the 4g63T intake manifold. |

| MD306269 | Pipe, Water Pump Inlet | 1 | 4g63T Pipe from water pump to thermostat | Since the 4g63T thermostat housing is mounted around the side of the block instead of on the front, you need this properly angled pipe. |

| MD024719 | Valve, PCV | 1 | 4g63T Positive Crankcase Ventilation valve | Even if you don't plan on using this, you need something to screw into the hole. |
| MD194888 | Cover Assy, Rocker | 1 | Valve cover from a 4g64 Galant DOHC | Any 4g63T valve cover will work, but this one doesn't say 2000cc on it (2.0L markings)! |

| MD186785 | Gasket, Rocker Cover Spark Plug Hole | 4 | 4g63T Gaskets for the spark plug openings | You don't want oil in your plug wires do you? |

| MD130704 | Bolt, Rocker Cover Washer Assembled, 6x1 | 5 | 4g63T Center spark plug cover bolts | Needed to mount the center cover (if you opt to use it). |
