I found this turbo and decided myself that it was close enough, here it is running on my 125cc 4speed Baja pit bike, all work was custom done by me about 3 years ago if I remember correctly. Came back here to update for 2025, this turbo is still working, i welded the water jacket closed because i wasnt using it on the dirtbike, i haven't had an issues with oil leaking or burning, everything seems to still be fine, granted i probably dont get more than a few hundred miles a year on the dirtbike, but i came here to buy two more to put on my ZX7R, so i guess ill see how that goes. For now, here is an updated video from just a few months ago when i was getting her back out of the garage for some riding.

I bought one of these turbos to install onto a 18hp Briggs & Stratton V-Twin. My initial reaction was wow that burns a lot of oil as in an entire quart of oil in 10 minutes! I mean it did make boost. After about 15 minutes of run time the shaft had so much play in it that the impeller hit the housing and destroyed the turbo. I contacted the company and they were nice enough to send me a second turbo. Upon installing the second turbo after about 5 minutes of run time the shaft straight up seized and no longer turns freely. It too also Burns a lot of oil. I recommend that you don't buy this turbo it is a complete waste of time and money. Go invest in a good one.

I bought one before and it was junk but i figured it was user error so i got another with the oil feed and drain kit because the last was spraying oil out of everything but even with everything done correctly it still leaks oil everywhere and is unusable
