i bought a used t3 garrett turbo and I'm trying to figure out what trim it is. The exhaust turbine has the following marked on it: 080104 6-6 and Garrett a/r 0.63 m-1. the compressor cover has the follwing numbers: a/r .50 806034 04E1. The compressor housing has the following numbers: 807096 04C1 and NB026. It uses a 4 bolt down pipe and an external waste gate.

anyone?

pull the compressor cover off. measure the inducer. Whatever number you get divide by 60mm or 2.36 which is the size of all T3 exducers, then square the number and multiply by 100 to get the compressor trim. This will apply to any other turbo, except that different family of turbos will have differnt sizes for exducers.

you gotta keep it in the same measuring units. don't mix and match. got it?

i measured the inducer and its 50mm. This equals out to 69.44? The diameter of the exducer was larger than 60mm, it has the marking of 04e1 marked inside the compressor housing. What size is the exducer of an 04e?

Not all T3 turbine exducers are 2.36". Heres a list of a bunch of common T3/T4's that are NOT 2.36"/60mm.
