By 2007, Nissan's ambition to increase the competitiveness of the Z33 chassis in Super Taikyu racing resulted in the development of a larger displacement engine based on the original VQ35HR Block. It featured the same bore but longer-throw crankshaft (bore × stroke: 95.5 mm × 88.4 mm). The end result was the VQ38HR powered Nismo Type 380RS-C which went on to dominate ST class 1 racing. The 3.8-liter racing engine in

The new engine block retained the same bore and stroke, but the connecting rods were lengthened and the block deck was raised by 8.4 mm to reduce piston side-loads. This modification, along with the use of larger crank bearings with main bearing caps reinforced by a rigid ladder-type main cap girdle to allow the engine reliably rev to 7600 rpm. With an increase in compression ratio from 10.3:1 to 10.6:1, these changes add 6 more horsepower (306 hp (228 kW) total + 3 hp ram air effect not measured by SAE testing = 309 hp (230 kW)).
