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 re-imagined coolant passages, there has never been a stronger 2J block available.

Based off the ever so popular OEM Toyota 2JZ engine platform, 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.
