1. The Evo VIII turbo will not fit the Galant VR4 as a bolt on solution. 2. The first reason for this is the direction the turbo faces is opposite the normal direction. 3. The second reason for this is if bolted straight to the block in its normal position, the downpipe would have to be in the space taken by the lateral subframe support due to the exit of the O2 housing of the flipped turbo. 4. The oil feed, water lines and return lines are in totally different locations compared to the factory setup. 5. Various other clearance issues will prevent proper mounting of the turbo making it impossible.
Step 1 - Acquire tubular Evo VIII manifold and Evo VIII turbo/O2. Step 1 completed. DNP Manifold acquired. Evo VIII turbo w/10.5 hotside acquired.
Step 2 - Cut the turbo mounting flange and rotate it 180 degrees, lining up the symmetrical holes of the flange with the hacked pipes and reweld. Not completed.
Step 3 - Downpipe should now sit in near factory location +3-4 inches due to shift to the drivers side of the flange in relation to the manifold.
Step 4 - Hack centers of water lines and return lines if necessary to accommodate new route for lines.
Step 5 - Use Stainless flexible feed line from oil port to top of turbo.
The exhaust side of the turbo would sit significantly closer to the radiator as the turbo would be facing the wrong direction. Normally, the exhaust side is tucked under the manifold close to the block but now it would be facing outward an up a bit. The O2 housing would still fire in generally the same direction and may allow for some cutting of the manifold runners to better square up the turbo in order to bring the exhaust side in a bit, closer to the block. The downpipe will have to be modified to line up with the new rotation and position of the O2 outlet, again, not a big deal. I have already flipped the alternator to the rear with a JayRacing kit so my clearance on the current hotside is very good. More clearance could be gained with a forward facing oil filter housing but my early estimates are that it wont be needed. The water and oil lines are a simple solution so no need to worry about those honestly. The other major consideration is the direction of the turbo compressor outlet. I believe a new pipe would have to be fabricated to redirect the compressor outlet towards the front of the car, again, an easy solution.
1:17 - Restate my assumptions.

5. All of these obstacles can be overcome.
Enter Evo VIII Turbo Experiment. I shall update this individual to my build post.
