From start to finish, I received constant updates, pictures, and videos throughout the entire process—something you just don’t get at other shops. John’s video proof and meticulous attention to detail make it undeniable the level of care and precision he puts i... read more

I was on the fence about a Coyote swap for my classic Bronco, but John convinced me it was the best move. He explained every detail, kept me updated, and built a truck that’s now a perfect mix of modern power and classic styling. It’s a whole new beast now.

John turned my Grand Cherokee into a Trackhawk killer—this thing is an absolute monster. AWD grips hard, the supercharger screams, and nothing on the road can touch it. If you want a real Hellcat Jeep swap, MasterTech is the only name you need to know.

John did the first-ever LS1 swap in a Jaguar XJ-S, and it’s a perfect fusion of European luxury and American muscle. The custom mounts, wiring integration, and tuning make it feel factory-built—but with way more attitude. This is the definition of high-performance innovation.

DO NOT TAKE YOUR CAR HERE! After more than a year and several false completion dates and more excuses than I can remember I was notified that THEY were going to deliver my car. Come to find out the reason they delivered it was because it wasn't safe to drive. * First - no exhaust...something about it being above their skill set. * Engine leaks oil. * Cut hood release cable. * Missing fog light cover and washer fluid tank? * A/C & cruise control wasn't a problem...then it was, neither happened. * Got a push button start I did... read more
