About Us


Grumpys Performance Center is a One-Stop Service and Dealership Alternative. We have been rebuilding quality engines for over 25 years. We pride ourselves on the continuous quality of our workmanship. We employ state-of-the-art equipment in our new 40,000 square-foot machine shop and warehouse located in Oregon. We are both ASA and Engine Pro certified. We are the #1 Diesel and Gas Engine Remanufacturing Machine Shop in the Northwest and we are now happy to be expanding our services NATION WIDE.


As you can see, we have a large warehouse and an actual location, not some apartment with a guy working on a laptop. We are a well established business that has been operating for over 25 years and we aren't slowing down any time soon!


Remember...PERFORMANCE is our middle name!
