Mazworx Pro Street Billet SR20VE RWD Block

The Mazworx Pro Street Billet SR20VE RWD Block is engineered to deliver exceptional durability and performance for both street-driven vehicles and competitive street racing applications. Designed as a direct replacement for the OEM block, it maintains the original appearance and fitment, making installation straightforward and hassle-free for Nissan SR20 enthusiasts.

Crafted from high-quality 6061-T6 aluminum, this billet block offers superior strength and heat resistance compared to the OEM cast block. Its advanced construction ensures enhanced line bore stability, critical for maintaining precision under elevated engine temperatures. This is further reinforced by the use of 4140 chromoly steel main caps, which reduce line bore growth by half from room temperature to operating temperature relative to aluminum caps, resulting in improved durability and engine reliability.

Optimized for maximum cooling and robustness, the block incorporates Darton Ductile Iron MID sleeves specifically designed for this application. These sleeves not only provide superior wear resistance but are also replaceable, allowing for easier engine maintenance and extended service life.
