I ordered a nissan 2.5 engine 2002-2006 When it arrived, I had it installed by a Professional Shop.Engine ran like Crap, Viberated like crazy, found out very low compression and they had not installed and/or purposly removed the balancer shafts within the engine. (obviously to save money) They claim to prevent future problems, B.S. I called complained they sent me another engine not until i had sent the old one back. which took weeks also i had to find a crate for the shipper to take the 1st engine.
When the "New Engine" arrived I had the same problems. So basically I had to pay mechanic twice to install 2 engines and in the end im still not satisfied. If you need an engine look else-where. There are engine builders that will also pay for installation if something is not right and also within the warranty period The Employees names of Engines-usa are as follows. Simon sales guy who often answers the phone when you call them, often doesnt know details about engine or what going on behind the scenes. Michelle prepares the shipping, and the owners name is Sam or sammy he is also the Engine builder. Indian guy. He sucks at what he does.
