Mitsu switched to Garrett TR30R on their WRC car when they hired the European dude (I forget his name, I believe he previously ran one of the French WRC programs) to run their WRC program a few years ago. They had been using Mitsu turbos up to that point due to pride but knew they were a liability, performance-wise.
You wouldn't want a WRC-spec compressor wheel on your street car. They have very little mapwidth, not a lot of ultimate flow capability, and low-ish efficiency at low pressure ratios. This is because the wheels are intended to be used with (and are therefore designed for) the inlet restrictor. They shine at very high pressure ratios, which is what you get when you add the inlet restrictor.
The TR30R turbine, on the other hand, would be very nice on a street car, better overall than the plain-jane GT30R wheel...

A TR30R would be built to your spec. The WRC spec TR30R is only one of hundreds of configurations that the turbo can be used for. Gale Banks used TR30Rs on both of his Diesel race trucks, one a road race Duramax and one a drag race duramax. Both the Audi and Peugeot diesel LMP cars use TR30Rs, the AER 2 liters use the TR30R, all with different restrictors. Its a versatile turbo and if you were willing to pay the money, it would be configured to exactly what you needed it for (much like anything in motorsports)

No that isn't evo VI Gr.A car engine bay;
that is evo VII WRC 2002.
I got in my hand the WRC '02 turbo and the ex cast manifold; I can tell you those parts are pieces of art.
I got from mitsubishi factory team few parts icluding the awesome tarmac brake
calipers and rotors.
that is evo VII WRC 2002.

Well, I had a good day, I went to see a guy who had a turbo from a 2001 Ford Focus WRC car.... Then bought it!
Spec as follows
Garrett TR30R
Compressor housing:
.60 A/R
60mm inlet
50mm outlet
Compressor wheel:
45.5mm Inducer
69.4mm Exducer
Turbine housing:
.57 A/R
50mm V-band inlet
60mm V-band outlet
Turbine wheel:
59.3mm
52.2mm
I lost the formula to work out trim, has anyone got it, or can tell me what these work out at?
It still has the FIA 34mm restrictor, but that can get bored out and release the full potential of this thing! Cool points to notice include:
-It has a cast stainles turbine housing
-The compressor wheel is CNC machined!!!!!!
-This is the same turbo used on the Audi R8 Le mans cars
The goodies
The turbo is part stripped as it was used for development and dyno testing. I'll get it
reassembled and balanced and then figure what to build to put it in!
The same guy had this manifold off the same 2001 Fucus WRC, but I couldn't afford it, and it needs modification to fit on a 20v!!!! But it is ****, and it all made of Inconel. Note the sensor lugs on all of the runners.
I may have it anyway and see what I can figure with it.
