HKS Complete VR38 Stroker Step PRO+ Crate Engine | 2008-2021 Nissan GT-R (23011-AN016)

2008-2021 Nissan GT-R Complete VR38 Stroker Step PRO+ Crate Engine by HKS

HKS comes through again with the VR4.3 Step PRO+ crate engine. This crate engine is the best on the market and comes with a ton of goodies including, oversized main stud bolts, beryllium valve seats with phosphor bronze valve guides, and high lift camshafts. This is the ultimate VR38 crate engine, and its performance will show you why.

For the complete engine VR4.3 STEP Pro+ that is capable of even higher torque, a special I-Beam con rod was developed that has a higher buckling strength than the H-Beam con rod. In addition, specially designed crankshaft to further increase torsional rigidity. The area of the dangerous cross-section is enlarged by a larger pin diameter, and the asymmetrical design of the critical section between pins #5 and #6, where the stress is highest, the thickened only. This minimizes the increase in weight and optimizes the balance ratio by reviewing the counterweight to match the increased weight of the pin section.
