That is the whole idea! If it fails, it is cheap to replace.

The second just got shipped out for testing. I should know more in a few days. I am told if it is a defective turbo from the factory, they will just replace it with a brand new one. Possible/potential 2.9% fail rate if I count the one in the UK. If I do not count it, 1.5% potential fail rate. I'd play those odds.

Do you guys offer a china version of a 30r?

I can get:
1. 3076 with T25 flanges, and externally gated. 0.86 a/r.
2. 3076 with T25 flanges, and internally gated. 0.86 a/r.

We have used the 2871 equivilent also. But no 3071 turbo.

What was the spool like on the 2871? Have you used the china 3076? If so, what was the spool like?

That seems like kind of a shitty combo. Tiny T2 inlet on a .64ar turbine housing combined with (what appears to be) a t04e compressor wheel.... So it would....spool poorly because of the large compressor and....have a shitty top end because of the tiny turbine housing.

Skip it.

(question directed to jeff)
Sorry to thread jack, but I am curious, that turbo you have which I also own is it comparable to a 30r?

The t28 your wondering about is great!!! I have ran one for about 500 miles now and its good, but my buddy has had one for a while now. The only problem he has had is that a bolt sheard off into the exaust housing. But the turbo works great!!!

.64ar .86 ar

.64ar on a t25 is roughly equivalent to a .48ar on a t3...except, you know, smaller. I have no doubt that the garrett model with a .86ar would be a good match, but tiny turbine + tiny ar + BIG compressor = a bad combo.

Edit: To clarify, the turbo in the ebay listing comes with a .64ar housing, while the standard garrett 2876r comes with a .86ar housing.

Wouldn't be very hard once it cooled off. I can remove the thing completely in about 15 minutes.

Funny, my oldest cat has gotten into a bad habit of where she does try to take chicken off my dinner plate (she gets super excited when I bring home charbroiled chicken), and she did take a chip off my plate once when I was sipping on a margarita while enjoy fajitas & salsa.

We have not dyno'd a Chinese 2871 yet. There are a few being used, but no dyno sheets have filtered back to me. No idea what spool was like, sorry.

We did receive our first confirmation of a Chinese turbo failure today. It is being replaced under warranty. Customer gets a brand new turbo. Other than it has excessive shaft play I do not know specific details, other than it failed.
