I run an Evo III 16G turbo, which is just a lighter and faster spooling Big 16G for the most part. It could be a c on the designation. I don't know the mistubishi turbos that well, but they did/do have a 14b turbo. Most of the G series are even numbers, 16, 18, 20, etc... so I'm not sure what the heck youa re looking at. If you want info on it talked to someone at Slow Boy Racing or ForcedPerformance.net as those are BIG DSM/Mitsubishi turbo houses and they may have some info for you to work with.
