The engine features innovative plasma - sprayed bores replacing cast iron liners for reduced
friction, lighter weight, enhanced cooling, power output and fuel efficiency; a symmetrical independent intake and exhaust manifold system featuring twin
high - performance IHI turbochargers; a secondary air management system for improved cold - start emissions performance; a thermostatically controlled oil - cooling system; an oil scavenger pump to
maintain oil flowing to the turbochargers; and a lateral wet and dry sump oiling system.
