We are sorry about this. The item ordered was out of stock, and soon as we were able to verify that we provided you with a full refund
Engine/Transmission ordered stated 45-60k miles. After inspection of motor(scoped cylinders found no cross hatch on walls and one burnt piston).Performed compression test(#1-26lbs-#2-31lbs-#3-62lbs-#4-102lbs-#5-58lbs). Informed JDM engine zone and they refuse to issue a full refund. There warranty stated any problems with engine(catastrophic failure) and they will have engine picked up and issue a 100% refund. JDM told me to install the engine and see how it would run.Who in there right mind would ask someone to install a bad engine before giving a warranty.Had to get a lawyer and in process of suing for a refund that should have been issued without a problem.

Hello, Thanks for reaching out. When the engine was first received in the Northwest the customer stated that there was silicone on it and they wanted to return for that reason. Even for a low mileage engine, if an engine is used it will signs that it has been used and silicone is a normal occurrence in used engines. Moreover, that silicone was present in the actual picture of the engine they saw prior to purchase. We suggested the customer to install it. After that the customer reached out to us stating the engine had poor internal performance. We asked for any type of video evidence to submitted as proof for management in the form of a compression test. They refused and this point there was nothing that can be done on our end. We need documentation of performance issues before a return be authorized.
Transmission was not delivered for nearly a week after I was promised that it would be when I ordered. When I called to enquire about delivery I was spoken to rudely and told that anyone near the phone answers it and "incompetent people answer our bussinesses phone and you shouldn't have made plans going by what you were told"

Hello, we are sorry you had a bad experience. Please keep in mind our average turn around time is 3-5 days and you wanted the item in less than 48 hours
The timing chain was so loose it was falling off the cam gears, and there was a lack of compression in cylinder 2. They refused to honor their warranty and obviously did not inspect the engine, otherwise these problems would have been obvious. I will never buy from this company again.

All of our engines are tested and inspected. Spark plugs should always be changed prior to installation. That is just good practice.
