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 are also recommended.
For the racing enthusiast or those just looking for the best, this is the ultimate upgrade to fully maximize the power output of your F87 M2. 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 are rebuilt factory turbos that are machined to Dinan specifications along with an upgraded thrust system to ensure reliable and prolonged life.

Core Program: Turbochargers are a part of the CORE program we utilize at Dinan so you will be charged an additional fee on top of MSRP initially. This fee will then be refunded to you once your old turbochargers have been received at Dinan and passed a quality check. This ensures we have a continuous stream of product for rebuilding purposes and the lowest possible price to the consumer. Any cores sent back that are damaged and/or unusable will not be given credit for. Please ensure adequate packaging and packing is being used to protect returning cores.
