Here is a quick add on to what Steve wrote a few years ago. You would be amazed at the number of phone calls that we get with people asking us to help them identify their turbo.

Let me RESPECTFULLY say this first. Trying to identify your turbo after you have purchased it is like buying shoes that you dont know what size they are and hoping they fit when you get them. No matter how good of a deal they are if they dont fit it isnt a good deal.

Here is a quick reference guide with compressor and turbine wheel measurements:

T3 Compressor Wheels
Inducer dia. Major dia.
35 trim 1.396 2.367
40 trim 1.484 2.367
45 trim 1.595 2.367
50 trim 1.674 2.367
55 trim 1.760 2.367
60 trim 1.830 2.367
Super 60 trim 1.900 2.367

TO4B Compressor Wheels
Inducer dia. Major dia.
Super-S 1.904 3.00
Super-V 2.180 3.00
Super-H 2.300 3.00

TO4E Compressor Wheels
Inducer dia. Major dia.
40 trim 1.870 3.00
46 trim 2.003 3.00
50 trim 2.122 3.00
54 trim 2.168 3.00
57 trim 2.227 3.00
60 trim 2.285 3.00

TO4E Super Compressor Wheels

62-1 2.441 3.00


T-Series Compressor Wheels
Inducer dia. Major dia.
HP-58 2.293 3.304
HP-61 2.418 3.228
HP-66 2.580 3.584
HP-70 2.733 4.030
HP-72 2.840 4.030
HP-76 2.941 4.030
HP-78 3.070 4.030


Turbine Wheels
Exducer dia Major dia
F1-49 1.929 2.320
F1-54 2.126 2.555
F1-57 2.244 2.555
F1-62 2.441 2.795
F1-65 2.559 2.920
F1-68 2.677 3.111



Another common question we get is how do I tell if I have the new F1 style turbine wheel. Please see the pictures below. The F1 turbine wheel has a taller tip height and is the wheel to the right in each picture.

Lastly when measuring you wheels please be sure to use a micrometer. You CANT get a accurate measurement by using a ruler or tape measure.

Unfortunately that serial number is too old to be in the build computer. We would need the wheel measurements outlined in this thread to identify the unit

[toy_21]
