Product Details
For the racing enthusiast or those just looking for the best, this is the ultimate upgrade to fully maximize the power output of your EWG N55ย engine. The compressor wheel inside theย turbochargerย isย increased in size allowing ~30% greater flow thusย enabling additional boost pressures at higher engine speeds while retaining efficiency.These are fully cast turbos that are manufacturedย to Dinan specifications along with anย upgraded thrust system over the stock turboย to ensure reliable and prolonged life. In order to attain maximum advertised power gains these big turbos will need to be paired withย DINANTRONICSย Stage 4, as well as Dinanโs intercoolerย to fully regulate the boost increase and deliver a polished product although the exhaust and intake areย also recommended.ย
