The 2000hp+ 2JZ Reinvented: Aftermarket CAST IRON Block

Say goodbye to the age-old saying "cast ain't fast" with Dart's 2JZ cast iron engine block.

When it comes to the many limitations factory cast blocks have when we try and take them from 200-300hp to 2000-3000hp or more, the go to option in the aftermarket is generally a billet alloy block that offers more strength and improved design (sometimes application specific), but at a substantial cost given the nature of manufacturing.

On display at SEMA, Dart has come to the rescue with their newly developed cast iron engine block which gives us a middle option where we can gain many of the advantages we get with billet offerings, namely design improvements that address known weak points, for a lower cost,. This allows us to safely produce more power and also gives us a reliable source for replacements if the worst does happen as secondhand factory 2JZ blocks become more scarce with time too.

With this block, you can expect added thickness to the bores and deck surface, reduced core shift, and a billet 4-bolt cap (centres are 12mm, outers 10mm) for improved strength as well as screw-in freeze plugs helping prevent a blow out which OEM press-fit versions sometimes do after a head lift. Additionally, the block can be clearanced to take alloy rods, making it perfect for those running stroker combinations and it retains the ability to run your factory accessories when it comes to oil and water pumps etc.

So farewell to some of the traditional opinions we all have when we hear the words 'cast block' with this affordable option to gain more power while still maintaining strength and durability. We're hoping to see these on the market in late 2023 for around $4200 USD.
