My kit arrived without instructions. I had to reach out to AAM, and what I received could not be called instructions, should be called notes. I had the exhaust parts ceramic coated and when I installed the turbine housing back on, noticed the turbine blades were broken. Contacted ConceptZ and they tried to reach out to AAM. Took another look at the compressor side and one of the blades is damaged as well! Still no word from AAM. Lastly, I am missing parts for oil feed. Avoid AAM
