But then you have to also take into account threads like this where Pure Turbos defends their turbo comparison:

Same brand as those n54 billet BB cartridge turbos that popped up, which had failure problems. Also, 59x78 is the size of our in house engineered PS2 compressor wheel. I surely hope your wheel profile doesn't exactly match our solidworks file created here in our facility. We will be checking on that. Also, FYI your cartridge is missing a heatshield in your pics!

Point is, do your research. I have been researching all of the turbo options for months and still haven't reached a decision. Be smart and do your homework before investing and trusting your car with one of these options.
