Mazworx SR to GM Midplate

The Mazworx SR to GM Midplate is a precision-engineered solution designed to facilitate the mounting of a GM bell housing onto a Nissan SR20 RWD engine block. Crafted from durable 1/2″ thick 6061-T6 aluminum, this adapter plate measures 24″ x 24″ to provide a perfect pattern alignment between the GM bell housing and the SR20 engine.

Unlike typical SR20 engine orientation which features a lean towards the exhaust side, this adapter plate repositions the engine to sit straight up, making it particularly suitable for chassis drag racing applications where alignment and balance are critical.

Key Features

• Constructed from high-strength 1/2″ 6061-T6 aluminum for durability and precision.
• Dimensions are 24″ x 24″ to match GM bell housing to SR20 RWD block bolt patterns.
• Corrects engine orientation to sit vertically instead of the factory lean toward the exhaust side.
• Includes engine bolts for mounting convenience.
• Requires trimming of the outer profile by the installer to fit the specific chassis.

This adapter plate is ideal for custom builds and conversions where it is necessary to mate a GM transmission to a Nissan SR20 engine, specifically in S13, S14, and S15 chassis platforms. Installation requires trimming to match your chassis profile and some fabrication knowledge.
