DG Built engine replacement customer review
★★★★★

Brought my car to Frank at DG Built with a blown engine. He found me an engine, got the old one out, and had the new one installed and ready to go in about a week and a half. The whole process was smooth, communication was great, and the work was flawless. I’ll 100% be bringing my car back for every service now.

★★★★★

DG Built Performance FTW! I have dealt with plenty of shops, mechanics, and builders, and Frank stands above them all. His patience, communication, and craftsmanship are something I hope many more people get to experience. The car runs like stock down low with no crazy boost curve up top. Mint!

DG Built BMW M4 customer review
★★★★★

Huge shoutout to DG Built Performance for the outstanding customer service and incredible work on my BMW M4. Frank installed my downpipes, replaced the spark plugs, and worked closely with Bend Calibration on custom tunes that are spot on. The car has never run better.
