cant identify turbo size
A friend of mine purchased a turbo locally, but the original owner told us that the size was a 76 trim hybrid. Thats how he described it. The compressor housing is pretty large, but the turbine is small for a twin scroll T4. We took the housings off today and measured the wheels. The compressor wheel measured 2.3" inducer and 3.3 exducer". The turbine wheel is 2.9" inducer and 2.5" exducer. We used the trim formula for the compressor and came up with 48 trim.

Re: cant identify turbo size
From a little searching it looks like its probably a t4 P trim turbine wheel.
Looking on this list http://fc3spro.com/TECH/TURBO/tmodels.html
It looks like it may be a Turbonetics T-58 / TS04
More precise measurements would make it more definite though.

Supposed to be the compressor map.
And the notes from that.
Alright I'm done.

Turbonetics T-58 / TS04
The TS04 is another popular pick for the 13B, and compares with the 60-1 and the T04E "60". Looking at the compressor map, it looks very similar to the T04E "60". The 70% efficiency plateau isn't explicitly labeled, but it's probably the line in between the 65% and 75% lines. Notice that the TS04 goes a lot higher than the T04E "60", so the TS04 can make power at really high boost - 30psi to 40psi+! On a 13B, the TS04 puts up similar numbers like the 60-1 and the T04E "60" - 400hp at the wheels on a DynoJet.
