I just picked up a t3/t4 from this guy for cheap. It's in good condition. My questions is, how can I find out the specs on this turbo? Is it in the number on the housing? Any help would be appreciated.

Measure the wheels, then go here to find out what wheels they are.

If you look on the comp. housing, you should see .50, .60, or .70 on it. .50 is usually a T04B housing. .60 is usually T04E. Looking at the turbine housing, if it's a true T3 housing, should read .36, .48, .63, or .82 a/r.

Thanks for your reply. The numbers I see on the turbine housing are 78-11830 and D2 2 070. The numbers on the compressor housing is 79-04000, 15253 and lastly a 4. How do you measure the wheels? Disassemble it or measure the inlet and outlet? Thanks again.
