BMW 335i Build: 600BHP Monster

BMW 335i Build: 600BHP Monster

The BMW 335i is one of those cars that quietly carved a legacy. Launched in the mid-2000s, it bridged the gap between daily usability and serious performanceโ€”especially thanks to the N54 engine, a twin-turbo straight-six that quickly earned a reputation for being far more capable than BMW let on.ย Fast forward nearly 20 years, and itโ€™s still a favourite in the tuning world. Why? Because it responds beautifully to upgrades.

When this particular 335iโ€”nicknamed the Green Beastโ€”rolled into Xatrix, we knew it wasnโ€™t here for a routine service. The owner had one goal in mind: to take this already iconic platform and elevate it to new levels of power and fun.

Cue the real stars of the show.


Enter the Twins: TTE600 by TheTurboEngineers

A build like this needed something serious under the bonnet. Thatโ€™s where theย TTE600 turbochargerย from TheTurboEngineersย came in.

These aren't your run-of-the-mill upgrades. Built with performance and precision in mind, theyโ€™re designed to bring out the best of the N54 engineโ€”unlocking the potential for 600bhp+ with the right supporting mods. Smooth spool, strong power delivery, and reliability that lets you push hard without second-guessing.

In other words, proper kit for proper power.

The Green Beast Gets to Work

With the twins in hand, our team at Xatrix got busy. Every seal, hose, bolt and fittingโ€”handled in-house with the level of detail and care weโ€™re known for.

This wasnโ€™t just about slapping parts on. It was about bringing a nearly two-decade-old engine platform into modern-day performance territory. And letโ€™s be honestโ€”600bhp from an N54? That still turns heads.

But the beauty of this build isnโ€™t just the number. Itโ€™s how it drives. Smooth off-boost, wild when you want it to be. A proper sleeper that still looks civilโ€ฆ until you hear the turbos spool.

Weโ€™ve got more parts coming for this one too, so stay tuned. The Green Beast isnโ€™t done evolving yet.


Final Thoughts โ€“ A Green Beast Like No Other

With the TTE600 turbos now under the bonnet, this BMW 335i is no longer just another 3-series. Itโ€™s louder, faster, and ready to take on anything. Watching this car evolve has been an absolute thrill, and we're stoked to see what else we can pull out of this iconic N54 engine. This might be just one of many epic builds we've done at Xatrix, but itโ€™s certainly one weโ€™ll never forget.
