Along with the aluminum bearing housing (which is also much longer) they have ceramic bearings vs Garrett's steel, metal retaining clips vs Garrett's plastic and dual, redundant seals on compressor and turbine side vs Garrett's single seals. Assuming they took care of the shattering turbine issue from a producer not following spec on their alloy, these are looking to be extremely reliable.
Looking forward to those Evo results too.
