That Racing Channel is building a Nissan R32 GTR and needed a powerful engine. So they turned to Mark Mazurowski at Mazworx for a built RB26/30 inline-six capable of 1500 hp (1118 kW). The build recipe started with a prepped RB30 block fitted with Nitto stroker crankshaft, Nitto rods, CP 9:1 compression pistons, billet main caps, billet girdle, and dry sump. On top Mark installed a Mazworx Stage 3 RB26 head with Kelford 182SE camshafts, Ferrea +1 mm valves, and Kelford beehive springs. Watch Mark and his team at Mazworx build a 1500 hp RB inline-six.
