with honest, skilled work
A shop that treats your car
like it's their own
Revolution Engines & Performance started with a simple idea: auto repair should be done right, not rushed. Located in the heart of Ontario, we've built our reputation on technical skill, transparent communication, and a genuine passion for how engines work.
We're not a chain shop. We don't upsell services you don't need. When you pull into our bay on East Locust Street, you're dealing with people who care about the work as much as the outcome — and that shows in every vehicle that leaves our shop.
The difference is in
the details
Transparent Pricing
We explain the work before we start and stick to the estimate. You'll never see a surprise charge on your bill.
Quality Parts
We use reputable parts from trusted suppliers. Whether OEM or performance-grade, every component is selected for durability and fit.
Expert Craftsmanship
Our team has deep experience across a wide range of makes and models — from daily drivers to high-performance builds.
Your Schedule, Respected
We communicate clearly about timelines and work to get your vehicle back to you as quickly as possible without cutting corners.
What our customers
have to say
They diagnosed an issue that two other shops couldn't figure out. Honest, fairly priced, and they actually stood behind their work. I won't go anywhere else for my vehicles.
Had my engine rebuilt here and the difference is night and day. Smooth, powerful, and running better than it has in years. These guys really know their stuff.
Finally a mechanic who explains things in plain language instead of making me feel confused. They treated my car with respect and the price was exactly what they quoted.
