Well played swaptronics with two chinese turbos today.
Turns out that they play well with each other. I was able to successfully put the 46 trim .70 A/R compressor on the .63 A/R stage III turbine and the 57 trim .50 A/R compressor on the .84 A/R "P-trim" Turbine (2.92"/2.54") 76 trim turbine.
Obviously the largest of the "stage III" turbines doesn't even come close to this other monster. This thing is a beast. I suspect that the 76mm 57 trim compressor with the big turbine is a 450 HP turbo and the 76mm 46 trim with the "stage III" .63 A/R turbine is good for 300-350 HP.

1st turbo was a T3s60
2nd turbo was the T3/T4 chinacharger with the .63 A/R "stage III" turbine.
3rd turbo is a hybrid between the T3/T4 chinacharger and the T70 chinacharger.
Problem with the T70's is that they are really a 46 trim T4 compressor, flowing a maximum of around 40 lbs/min of air, where the T3/T4 chinacharger (and there are two different types... one good and one not so good.) had an honest to goodness 57 trim 76mm compressor wheel that should flow around 50 lbs/min of air in a .50 A/R housing. (The not so good one looks to have a 46 trim compressor as well.)
So obviously I wanted to use the P-trim(76 trim) turbine that came in the T70 2.92"(74.1mm)/2.54"(64.5mm) Turbine instead of the 68 trim 2.xx (I suspect 2.5x or so)/2.25(57.1mm) "stage III" turbine. Swapped the compressor housings and viola... new ghettohybrid.

You don't have to rebalance as the compressors are balanced independent of the shaft and turbine (or should be.) If it's off I will be surprised. Corky has it at the shop, I am trying to get it done. I leave for OIS in 8 days though and likely won't see the car until xmas.
