Dinan Big Turbos

Dinan Big Turbos are the ultimate upgrades for racing enthusiasts to fully maximize the power output of your engine. The compressor wheel inside the turbocharger is increased in size enabling additional boost pressures, and thus increased horsepower at higher engine speeds--all while retaining efficiency. These are with an upgraded thrust system to ensure reliable and prolonged life. They are available as brand new units with a new stock turbine custom cast and manufactured, or as rebuilt factory units machined to Dinan specifications. Both come with an upgraded thrust system to ensure reliable, prolonged life.

Dinan Big Turbos feature:

* Larger billet compressor/impeller wheel that allows 30 percent greater flow over stock which then enables additional boost to be realized while retaining efficiency.
* Dinan Installation instructions detail a procedure which is quicker than BMW's turbo replacement procedure saving the end-user money and time at the shop (Applicable to RWD vehicles only).
* Includes O-rings and gaskets needed for complete installation on a RWD vehicle only.
