Overview

For the racing enthusiast or those just looking for the best this is the ultimate upgrade to fully maximize the power output of your MWG N55 engine. The compressor wheel inside the turbocharger is increased in size allowing 30% greater flow thus enabling additional boost pressures at higher engine speeds while retaining efficiency. These aren't standard rebuilds but rather brand new units with a new stock turbine custom cast and manufactured with an upgraded thrust system to ensure a reliable and prolonged life. In order to attain maximum advertised power gains, these big turbos will need to be paired with DINANTRONICS Stage 4, as well as Dinan's intercooler to fully regulate the boost increase and deliver a polished product although the exhaust and intake is also recommended.

Features:

  • No core charge or core return is required.
  • Brand new upgraded turbo that is custom cast and manufactured with an upgraded thrust system. 
  • Larger billet compressor/impeller wheel that allows ~30% greater flow over stock which then enables additional boost to be realized while retaining efficiency.
