Yea, nearly everything is reputable...
I know that ATS trannies are reputable for breaking or not living up to expectations. Theres quit a few guys that have a fully built transmission and are on the third one in two years... not good in my opinion. And if it breaks or somethings wrong with it, good luck gettin them to fix it under warranty.
As for the turbos, I would say they are probably pretty good, I just wont do business with them because of their shoddy reputation concerning warranty coverage/work on transmissions...
