Chaviz’s Duramax started out with a lift and some fancy wheels and tires. It came to us first for a set of upgraded injectors and CP3. Shortly after he ordered an S300 turbo kit. After a few months of running it that way, it came in with a bent connecting rod on cylinder #2. You guessed it! We did a full motor build with Carillo rods, studs, and other motor upgrades. After that, the motor was just begging you to throw more air to it, so we went with an S474 on top of the S300 and let’s just say… wow!
