SKU: 041 Category:


This is the perfect option for our EVO customers who don’t have a useable 2.0 4G63 block which are becoming tough to get ahold of. The 4G64 block will work in ┬áplace of all Evo 4-9 including those equipped with the MIVEC system. This combination provides the best of both worlds; good torque and a higher RPM band than a 2.0L along with a more favorable rod/stroke ratio. ┬áThe 2.1 is built using a 4G64 block, 88mm stroke crank and +6mm long rods. All of our shortblocks are sold internally balanced and fully blueprinted. Please contact us if you have any questions or would like to discuss options.
