The RB25 is the baby brother of the RB26. Largely goes unnoticed and its potential is underestimated. However, did you know that our RB26 strokers fit directly into the RB25 block? The crankshaft and the connecting rods are all the same, only difference is in the piston!

Due to the popularity of the RB26 2.8L stroker kit, we have opted to only manufacture these kits in 2.8L capacity as opposed to both 2.7L and 2.8L

To date, the success of the RB28 kit can be seen on the circuit with various Open Class World Time Attack Challenge competitors utilising our kits. This application is arguably the most difficult application for any set of components to endure, given the punishing nature of circuit racing, testing the ability to maintain a certain level of performance over extended periods of time. Additionally, plenty of builds run the RB28 kit on the drag strip with considerable success and these kits can also be seen in street driven applications.

The kits consist of Nitto/CP pistons in either 86.5MM/+0.020" or 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 121.5mm I-beam connecting rods are included in both of the 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 RB28 4340 stroker crank is also included.
