This Darton engine block is constructed using a proprietary casting process that ensures superior metallurgical properties. The block features a nodular iron material, which offers increased tensile strength and fatigue resistance. The nodular iron material also provides enhanced dimensional stability, ensuring a precise fit and alignment of engine components.

One of the most notable features of the Darton DAR-800-800 block is its increased bore size, which is 80mm (3.15 inches) compared to the standard Mini Cooper's 71.1mm (2.795 inches) bore size. This larger bore size allows for more displacement and, consequently, more power. The block also includes a higher deck height, which provides increased compression and improved combustion efficiency.

The Darton DAR-800-800 engine block is also designed with enhanced cooling capabilities. The block features thicker walls and larger water jacket passages, which help to dissipate heat more effectively and maintain optimal engine temperature. The engine block also includes a provision for a baffled sump, which helps to prevent oil starvation during high-speed cornering or hard acceleration.

This engine block is designed to be a direct replacement for the OEM Mini Cooper engine block. It includes all necessary mounting surfaces and bolt holes to ensure a seamless installation process. The block is also CNC-machined to ensure a precise fit and finish.

In conclusion, the Darton DAR-800-800 engine block is a high-performance aftermarket solution for Mini Cooper engines. It offers increased strength, durability, and power compared to the OEM block, thanks to its nodular iron construction, larger bore size, and increased deck height. The block also includes enhanced cooling capabilities, ensuring optimal engine temperature during high-performance driving. With its direct replacement design and precise machining, this engine block is an excellent choice for Mini Cooper enthusiasts seeking to boost the power output of their engine.

The benefits of our miseries kits are: cast iron performance in an aluminum block. The manufacturing process of cast in sleeves provides for economy scale low horsepower engines, but does not accommodate high horsepower, boost, or larger bore sizes. Now that Darton has solved the design issue of cylinder weakness another with wet sleeves is exterior surface. Bulletproof Darton ductile iron.

There is a different engineering model for each engine and cylinder design. Darton pioneered modular sleeve designs and specialty ductile iron material beginning with our manufacture of top fuel sleeves for Keith black racing engines Milton engineering in 1978. The Darton mid sleeve kit is available for many series of 4, 6, and 8 cylinder import domestic engines provides maximum bore sizes boost potential. High boost and horsepower potential.

Picture is only for reference and may differ from actual product. Our mid design compensates for this high resident heat soak condition. Now with Darton mid, swirl coolant technology the cooling medium is ported and directed to significantly improve heat transfer where it needed most, in upper cylinder wall/flange area. EDP performance.

Wet sleeve replace-ability. Superior oil and compression control. This is like pouring water through a funnel, there really no flow or velocity until the exits spigot. Improved block integral strength.

Improved cooling. High rpm normally translates into efficient scavenging of airflow but during misfires or incomplete flame propagation, high cylinder pressures and temperatures are created. Heat is also dissipated through the use of register fins. Postage shipping is free for this item.

Free postage. 130,000-psi tensile strength. Inherent in open or closed deck engine blocks of cast iron aluminum is a certain amount water stagnation. The enhanced water flow in and around the flange area is possible because of ported control engineering we call swirl coolant technology.

In the normal dry sleeve installation cooling medium, water, must transfer heat absorption through block material and sleeves, which may be dissimilar metals. Increased horsepower output potential. This aids the elimination of hot spots in compression area allowing you to make more power. In the case of blocks and heads, casting ports are designed for ease not efficient flow.

This micro crystalline structure on the mid sleeve makes it optimal for corrosion and rust resistance. Superior cylinder sealing and ring wear. This coating resists abrasion from the hot turbulent water flow that is created in jacket area of block. Street or strip application.

In a standard wet sleeve design sleeves are punished by turbulent coolant often causing corrosion or rust. Phosphate coating is the treatment with a solution whereby surface of metal covered an integral, protective layer insoluble crystalline. In addition, Darton designs' manage and enhance water flow from block to head promote stability of cooling all sleeves are the wet design. Darton 800-800 mid sleeves for mini coopers engine block: this item is in stock and ready to ship.

Darton now supplies the mid sleeves with a phosphate coating.
