We do performance modifications on most Asian, American and European vehicles, including tons of worldwide vintage vehicles!

We are one of only a select few performance shops in Washington State that can professionally install a forced induction system on your vehicle. We can perform street tuning as well as dyno tuning on our engine builds to maximize your power gains.
We have extensive knowledge that allows us to swap more powerful engines into your car. We’ve done many custom engine swaps, some common some not so common! What engine can we swap for you?
We can install all types of brake upgrades for your vehicle. Whether it’s a large, 6-piston caliper brake conversion upgrade or simple high-performance brake pads, we can help!
Naturally Aspirated Engine Builds
We also rebuild stock engines for you daily driver, either in house or through a high quality stock engine rebuilder we partner with. These fully rebuilt stock engines come with up to a 7 year 100000 mile warranty!
The need for speed is only tempered by the need to be cheap. Don’t let that new build blow up because you didn’t know the gas you got was poor. The correct sensor gauges can help.
