We all don't. A lot of people on here like the g54b motor. Others, my self included, feel inclined to throw our g54's into the ocean.

 

G54b is an Astron series motor. Usually served in rwd/4x4 flavor.

 

4g63/4 is a Sirius motor, best known for its fwd/awd variants (called a narrow block)

 

Now the 4g63/4 wide blocks are Sirius blocks but for rwd applications. They also share a bellhousing pattern and motormount position with the Astron rwd motors.

 

In turn, a wide block literally bolts into the place of a rwd g54b. This bridges the gap between both worlds. It has been prophesized for years.

 

So you then can bolt on an eclipse turbo head/setup and achieve mpi, dohc, distributorless awesomeness. Use a 4g64 and gain .4 litres over an eclipse.

 

Sadly, the Mitsu gods didn't deliver enough wideblocks to satisfy the Mitsu race.

There's a dude in Australia that makes freeze press fit thermostat adapter to route the thermostat through the timing cover and towards the front of the engine. It is billet and looks sweet. Definitely a must if you don't want to run the small housing in the back and want to route coolant flow to the front
