Thread: Identify this turbo..

Finally had time to buy a digital caliper:
Compressor side
In. 53.1mm
ex.70.76mm

Exhaust
In. 53mm
ex. 46.2mm

.......x2

those look like 2871r specs to me. Here is what atpturbo lists as specs.

Turbine
-Wheel: 53.85mm w/ 76 trim
-Housing: .86 or .64 ar
-Maps

Compressor
-Wheel: 71mm w/ 56 trim
-Housing: .60 ar

btw the gt28rs and the 2871r use the same exhaust housing but the compressor housing is different in size only. Both turbos have the same options for comp housings.
