I made the mistake of buying this turbo I am not saying anything bad just what happened to me and you make your own judgement.
I bought this turbo in 2013 it worked fine about 5-6 months I started having trouble building air pressure after replacing the compressor and other things we found the problem the waste gate acuator shaft broke. It had been a while so thought it was the original one from my holset turbo. So Bought a new one and replaced. Then few months after that started leaking from the waiste gate seal then shortly after that I just lost all power and what do you know the shaft inside of turbo broke. Called them because it was just about 1 year give or take a week. All this company can say is ship it back but by the way you pay to ship back. So if you dont live within 1 hour drive to there location in Ca. My original Holset had over 750000 miles JM Turbo did not even make 100000.
