I've seen 14B's (standard TD05H - inconnel) do the same thing. In fact, the one I saw shot out the car's tailpipe and was sitting on the track after his run.

that is about 1,428.82 kgs. 
..... EVO 5 RS and EVO 6 RS (both came with a 16g6 and a 10.5T hotside) only weight 2,755.77 lbs. guess that is why they can get easily into the high 11s territory with minor mods.

went to the counterclockwise turbo on the version 4? Was it for gasflow, packaging???

With the engine on the other side of the engine bay, the exhaust gasses just want to flow in that direction. Plus it would have meant a big change to the engine bay if the turbo compressor were pointed at the other side.

I think that the other reason I gave was probably the major factor.
However, take a look at this picture:
When the gasses hit the exhaust manifold, they have to make a 90 degree turn to enter the turbo. Hopefully this is a gradual turn in the manifold. You will notice in the picture that the exhaust will immediately start to turn more, in the same direction as the 90 degree turn (back towards the engine) as it enters the snail of the exhaust housing.
If they instead mounted a normal rotation turbo on the car, the exhaust would have to make a turn in the other direction as it enters the snail. This would probably decrease the efficiency of the system. I think that with all the tiny tweaks that Mitsu has done to the Evo's 16G turbo over the years, that this probably was a small part of their consideration.

The RS’s where designed for competition use and have basic interiors and less sound deadening, that’s why they are lighter. This reduction of equipment leads to their slightly lower price as much of the equipment in the GSR’s are not wanted when you go rallying!
, with the larger RS rear diff and a LSD, with bigger driveshafts, etc. .....
