Show original supplier description
The 2JR QR25 Hi-Power RZ Cams represent the pinnacle of horsepower enhancement for the (2002-2012) QR25DE engine, a collaborative release from 2JR and JWT. They are capable of significant power increases, with claims of up to 235 whp on race gas. Installation of these cams requires a tune for optimal performance. Users should anticipate a loss of some low-end torque under 3000 RPM, estimated at -15 HP. However, the cams will provide substantial power above 5000 RPM and allow the engine to rev past 8000 RPM. A lopey idle is a characteristic of these high-lift cams, ensuring others will know your QR engine has been modified. It is important to note that the cam gear is not included and cannot be used with these high-lift cams. A matched RZ valve spring set is also required. These cams are available for both 2002-2006 (Gen 1) and 2007-2012 (Gen 2) QR25 engines and will fit Sentra, Altima, and Frontier models with the 2.5L engine.
