the early ones were utter shit but they have cleaned there act up now. out of about 10 early ones 2 failed, but have passed on around 70 of the newer type like shown in the listing and i havnt had 1 reported failure.

im not saying there anywhere near the league of garrett, just a cheap turbo to run on a cheap build at low boost. 1 was run at 30 psi for 4k miles and was getting well worn in the bearings with alot of endfloat so 2 bar is a no no for them.

i do agree though christian in that in a proper built and specced engine they arent worth the risk.
