Introducing the Nissan/Datsun M90 1.8L Bare Engine Block Z22 from the iconic 1100-Z22 (Datsun 720) series produced in 1981. This engine block is a testament to Nissan's engineering prowess during that era, delivering exceptional power and reliability.

The M90 engine block is a straight-4, SOHC (Single Overhead Camshaft) design, crafted from high-strength cast iron. Its compact dimensions make it an excellent choice for various applications, while its durable construction ensures longevity.

The engine block's design incorporates a wet sump oiling system, which ensures efficient lubrication for the engine's components. The block's cylinder bores are lined with Nikasil (Nickel Silicon Carbide) coatings, enabling excellent heat transfer and a long-lasting, wear-resistant surface. The block's cylinder walls are also designed with a pent-roof shape, promoting superior combustion efficiency and power output.

Additionally, the M90 engine block features a reinforced crankshaft bearing area and a thicker main bearing cap, enhancing the block's overall strength and durability. The block also houses an integral oil pump and a deep sump, contributing to the engine's robustness and performance.

This Nissan M90 engine block is a must-have for car enthusiasts, collectors, and restoration projects. Its classic design, combined with its proven power and reliability, makes it a valuable addition to any garage. Whether you plan to build a high-performance engine or restore a classic Datsun 720, this M90 engine block is an essential starting point.
