Many customers have bad experience with Made in China. Yes, we are Chinese manufacturers, but you won’t encounter the situation. The most important material and most of the cost in the turbo is Nickel. For example, the turbine wheel head should contain about 65 – 75% Nickel. To reduce cost, many standard manufactures only has either 30% - or sometimes as low as 15% Nickel in turbine wheels. You cannot visually tell the difference between these parts and the result is a warranty failure. We general use 72% Nickel alloys 713Ceven when replacing an OE shaft with lower grade GMR alloy. Please remember the important point, when you see products in EM packing boxes, you know you can trust them.
