I bought a used motor from them and it blew up after 5 minutes of use, because they cut the wire coming off the oil pressure sensor to hide the fact that the motor had no oil pressure. They deliberately bypassed the motors factory warning system to hide the fact that it was in need of serious repair. If the sensor was hooked up like it was supposed to be, the motor wouldn't of allowed itself to rev above 2100 rpms (limp mode). Because they cut that wire, the ECM didn't know that the motor wasn't getting any oil so it quickly burnt up the piston rings running with no oil in the cylinder. Their advertisement for the motor said it was "like new" with "low hours" and "ran perfectly" Which it did run great at idle at the shop, but once I ran it a half a mile at half throttle it blew up due to the lack of proper lubrication in the cylinders. There goes a few thousand dollars.
