Evo IX JDM comes with TD05HRA-16G6mC-10.5T
m denoting Magnesium wheel

TD05 = size of the mitsubishi turbo .. 03/04/05/06 denotes the size
H = high pressure
R = reverse rotation
A = Titanium alloy turbines
16 = size of the compressor wheels (arbituary number .. can't remember exactly what it means..)
G6 = number of blades / diffusers
C= compressor housing type
10.5T = size of turbine outlet housing ( ie 9.8 = 9.8cm^2 .. 12 = 12cm^2)

Stock X turbo compressor measures 68mm exducer and 47mm inducer (that or 45mm can't remember)

Only JDM GSRs (that includes SSTs and manuals) comes with titanium turbos ..

All the rest of the world (and JDM RS) uses TD05H-152G inconnel wheels

Not really sure where to put this. I figured here would be a good place.

I came across this on another forum. These are the JDM model turbo sizes, but should be the same for USDM models...
