Whether it be Japanese, Australian or European, Nizpro have long had a reputation for knowing how to tweak turbocharged six cylinder engines. This BMW 335i development mule has yielded fantastic performance results with minimal changes . The factory twin turbo N54 3L six six still retains standard engine internals and factory stock turbochargers. Removing a few of the breathing restrictions including the intercooler, now replaced by a Nizpro front mount and larger piping. Aiding airflow in and out of those small TD03 turbos are VTT intake pipes and VRSF cast dump pipes. The remainder of the exhaust is still factory BMW. The 3 series was initially run on a mix of E85 and unleaded petrol, but a recent addition of water methanol injection has allowed the car to be now run on straight E85. These modifications have seen standard rear wheel power jump from 162kw or 217hp on 8psi boost to a solid 305kW or 409hp running a peak of 21psi dropping to 15psi by redline, all tuned in-house using MHD Flasher.
