Few engines have left as profound of an impact on the world of performance as the 2J platform, and Dart has identified a significant void in the legendary inline-six performance platform’s needs. Introducing a completely new and improved design over OEM blocks that promises to take the most popular sport compact platform in the world to the next level!
Scheduled for release January 2024, our 2JZ Iron blocks come equipped with significantly improved features such as Siamese cylinder bores, a robust four-bolt steel main cap configuration, and an increased deck thickness – all meticulously engineered to ensure success during high-performance operation. With a comprehensive overhaul of the crank structure and reimagined coolant passages, there has never been a stronger 2J block available.

Based off the ever so popular OEM Toyota 2JZ engine platorm, Dart has taken a proven engine block, and made it even better. Revising the main caps from the 2 bolt cap design, to a 4 bolt cap design on 1-6 caps. Dart has increased the crankcase strength, providing a block that will work in 2000HP+ applications. We did not stop there, we revised and increased the cylinder wall, block deck, and outer case wall thicknesses, to help eliminate any failures under high boost applications.
