So I bought this gt2056 vnt turbo off a 07 Mercedes. I plan on putting this on my 86 mr2. The turbo is in great condition, but the compressor blade has some knicks on it. They are not too bad, but i want to fix it. I can not find one place that sells a gt2056 compressor blade. I am look at upgrading the blade to something i can find. The compressor blade bore for the turbine shaft is 5mm. t3's will not work because the turbine shafts are about 6mm. I have found a source for a gt2560 blade, but im not so fond of the map. Im also thinking about replacing it with g2860rs blade but i dont know if the turbine shaft is 5mm or 6. I know that starting at the gt30's, the turbine shaft is enlarged to 6mm. Also, I have not found a source for it. One other possibility is a td04-15t. these were used on turbo volvos 850. The turbine shaft is 5mm also. I might be leaning towards this because i think ive seen one at the pull-a-part. The only problem is that the bottom of the compressor blade on Mitsubishi blades look to have some sort of tapered hump on them. i could probably have it milled down if its not ceramic.
does anyone know where i can get some of these compressor blades? Also im a very cheap person, so the cheaper option is my favorite. This turbo is more of a fun project and to experiment with the new vnt turbos. i really dont care that much for power. If i cant find anything ill probably deburr the blades and just have it rebalanced.
