Place holder review. Only driven 37 miles so far.

What I liked: It's inexpensive.What I don't like: Sketchy as frig. Gaskets leave a lot to be desired.After watching a couple hours of BoostedBoiz videos, I decided maybe I could get away with a cheap turbo. After all, the real ones are probably made in the same town as this one is!Anyone who's at the level where they're changing a turbocharger is going to be able to address this thing's shortcomings. The worst thing I saw was the angle of the wastegate actuator arm was such that the circlip wouldn't set in it's land. I tried bending the arm on the actuator, but it snapped and I just used the stock wastegate actuator (after bending to sit on the waste gate arm properly.)Issue number 2: The stud that holds the water lines going to the heater core didn't come on this unit and I couldn't get the original one off the old turbo because I was drunk and lazy and just went ham with a pair of slip jaw pliers. Sooo, I just tossed a spare bolt in where the stud was.Issue 3: The swarf. There was more than a little swarf left over from machining the hot side. I'm guessing it came from the bores of the down pipe stud holes. Either way, the preserving oil held a lot of iron chips in the hot side, including on the turbine. If I cared more I would have taken the exhaust housing off and thoroughly cleaned it. The compressor side, as I'm sure everyone has figured out, doesn't always let the backup plate free without a fight so I didn't even consider removing the compressor housing to take a look around.I only have 37 miles on this unit. On startup the oxygen sensor freaked out from the burning preserving oil and the engine almost died, but after a couple minutes the idle smoothed out. I'm being gentle on this thing for a while because I need my car to get to work and because I think being gentle while it wears in is probably beneficial.The reason I didn't go with a legit Borg Warner CHRA was because of wide cracking around the wastegate opening on my exhaust housing. So, at least I should have a couple housings to go on a CHRA if this thing goes to hell!I'll try to update this when the car hits 1000 miles. I put everything together with Bostic pure nickle anti-seize for ease of replacement just in case.Consider buying downpipe spring bolt things, the cone gasket, and a kit of copper crush gaskets. Didn't come with an engine side gasket for the oil drain pipe.I'll tell ya what, I didn't make a mistake going into aviation instead of automotive. Those car mechanics earn their money.

Pros
  • Perfect fit
Cons
  • More frequent maintenance may be required to ensure optimal performance
