Dinan Big Turbo Upgrade for BMW N55 Mechanical Wastegate (MWG)
Unlock serious power and response from your BMW N55 with the Dinan Big Turbo upgrade. Designed specifically for the N55 MWG engine, this performance turbocharger delivers up to 30 percent greater compressor flow, allowing higher boost at elevated engine speeds while maintaining efficiency. It is the ultimate BMW N55 turbo upgrade for drivers who want reliable, repeatable performance on road or track.
Unlike a standard rebuild, this is a brand new turbocharger assembly featuring a custom cast new stock turbine and an upgraded thrust system for strength, durability and long service life. Pair it with DINANTRONICS Stage 4 tuning and Dinan's intercooler to achieve the advertised power gains and keep charge temps in check. An upgraded exhaust and intake are also recommended to support flow and maximise performance.
