Sleeper Performance

Sleeper Performance You Dream it we can build it. We offer engine building services, machining, custom parts, tuning, and full car builds. We specialize in mazda rotary engines, mitsubishi, honda, datsun, and ford.

everything from street to track performance. We can give you the edge on the competition on and off the street.


I know this isn't car related but it's very important because this is for a girl I've known for a long time who is losing her hearing. She's a wife and mother and really needs help and support. If you would please share and/or donate what you can, we can all help with this. Thanks you all! And have a great Memorial Day weekend!
