  • The RB 30 originally featured in the Nissan HR31 and the Holden VL Commodore in Single Overhead Cam (SOHC) configuration. The RB 30 has significant downfalls surrounding the harmonics of the crankshaft and integrity of the connecting rod and piston combination. To this end, Nitto saw the opportunity to advance this area of the industry and not only create a kit of billet components, but increase the capacity as well. Much like we have in other areas. These components held a series of world records.

    As such, the RB 30 3.2L stroker kit has become our flagship kit, that spearheads our range of components. With the use of the RB32 centred largely around drag racing, the vast majority of the world’s quickest and fastest GTRs and RB powered vehicles employ the services of our 3.2L stroker kits. In this area of our website, we present to you the standard connecting rod journal 3.2L stroker kits, which are extremely popular in a vast multitude of street cars and drag cars in the like.

    The kit consists of Nitto/CP pistons, with your choice of SOHC or Double Overhead Cam (DOHC), in either 85mm/-0.040″, 86mm/+0.000″, 86.5mm/+0.020″ and 87mm/+0.040″, cut from the Turbo HD forging, PVD Turbo ring set for the ultimate sealing capabilities and, of course, the CP 9310 wrist pins. Nitto 152.4mm I-beam, I1.5 and V2 configuration connecting rods are both available for the stroker kits and come with ARP 2000 rod bolts as standard. The option to purchase Custom Age 625 rod bolts is also available on purchase. Finally, the Nitto RB 30 3.2L 4340 stroker crank is also included in the kit, with the option to purchase the stronger EN40B material crankshaft in the same variation.
