Yeah. All the 16g's are slightly different. The EVO3 is lighter, and makes a little more top end power and has a slighty stiffer wastegate actuator spring. The EVO3 has the same turbine specs with a lighter turbine housing and has a slightly larger compressor wheel which is also lighter. Compared to the small and big 16g's of course. The HRC Super 16G is a little different
As for the Hahn Racecraft 16g's, I have no experience or input on these since they are modified mitsu turbo's. They do NOT carry the same specs as factory MHI turbo's, but I believe that the HRC "Super 16G" is very similar to the EVO3 in terms of CFM, spool time and efficieny. I'm thinking it has slightly larger turbine housing, increasing exhaust flow and efficieny over a standard 16G but that is almost always at the expense of spool time. None of the 16G's have much lag though.
Atleast a manifold will be easy to come by since it has a T3 flanged turbine housing
