i would do a write up but without knowing the compressor sizes and designs, wastegate sizes, bearings and other internals, shaft sizes or cutback angles its impossible to give accurate for and againsts of each turbo. ie, the tong turbo one has a bigger compressor intake but whether or not that means it has the best matched, or even biggest comp wheel is hard to say, as the others could have a simaler sized intake obtained from boreing out the compressor cover internally or using a compwheel with a bigger base. thats just an example but it shows the point.
also not knowing who built them or what specs they are balanced too doesnt help either.
the only way this thread can be accurate is for people to post power results and experiences based on using each turbo...or for the traders to give the full specifications of there turbos and the parts used...and the later aint gonna happen! lol
