Another dream build brought to life. 🔥

This BMW F20 M135i N55 came to us with one goal: build it right.

Every part on this build was supplied through Ultimate PSI. The customer chose our complete Ultimate PSI bolt-on package, including our Crank Bolt Capture for added protection and ACL Rod Bearings for maximum reliability. Any additional components outside our product line were sourced by us from the USA, giving the customer everything needed to complete his dream build.

To complete the package, we tuned the engine with bootmod3 , optimized the transmission with xAutomotive , and verified the results on the dyno to ensure everything performed exactly as expected.

The result? A compact xDrive monster that delivers incredible power, lightning-fast shifts, and unbelievable traction. This little beast is a perfect example of what the N55 platform is capable of when built and calibrated the right way. 💙
