R.O.T.S. Engines

Running On The Stand

Filling the gap between top end crate engines and junkyard builds.

Like many of you, I dont have the budget for a crate engine. I also dont want to spend time and money on a junkyard engine, or one that "ran when pulled", only to find out that it has an issue and have to pull it out and start over. Lots of aftermarket computer and wiring harnesses are out there, but cost as much as an entire OEM engine, harness and ECU from us.
