Complete Performance Upgrades for the BMW 335i & 135i N54

[vc_row][vc_column][vc_column_text]

The BMW 335i and 135i are great cars to upgrade if you’re looking for extra performance. The 3.0 liter turbocharged N54 engine can see massive horsepower and torque gains with the use of simple bolt-on parts such as a ECU Tuning, downpipes and a catback exhaust!

 

Catback Exhaust Systems

The engine is like an air pump; the more air that is allowed to flow through it, the more horsepower that you get out of it.  By upgrading to a catback exhaust system your engine will be able to move exhaust gasses more efficiently, allowing for increased horsepower, torque and exhaust tone.

Downpipes

ECU Tuning is a great way to improve a vehicles performance. A simple ECU flash will gain quicker throttle response, increased torque, faster turbo spool, and a top end that pulls very hard to redline. Tuning a cars ECU can be done in a variety of different methods which depend on the ECU or vehicle type. As for the BMW 335i & 135i  with the N54 Engine, we are able to safely adjust the parameters such as fuel, timing, and boost easily through the BMW’s OBDII port.

Turbo Upgrades

By modifying the compressor and clipping the turbine wheel, we are able to gain as much as 60+ Horsepower to the crank over the stock turbochargers with supporting mods. The process to modify the turbos requires precision machining and a complete dissasembly to rebuild the turbos.
