This product was designed for high performance without a loss in power at all engine RPM range and with a well-balanced power curve.
Using the valve spring specifically designed for the VR35DETT engine and this newly designed high lift camshaft can dramatically improve the performance.
Furthermore, once this product is combined with the HKS STEP2 Engine and GT800 Full Turbine Kit, the boost pressure can be increased much more smoothly and quickly, and the engine output can exceed more than 850ps.
