Overview

The Innovative Turbo Systems TMC02 is a turbo manifold designed for GM Chevy II vehicles with 194, 230, or 250 CID inline 6 engines. Constructed from cast iron, this manifold features large, smooth radius runners for optimal performance.

The collector bolt pattern is designed to accommodate a T3 turbocharger. However, it can be modified to fit a T4 turbocharger by drilling and tapping two new bolt holes and grinding the gas passage openings to suit the larger T4 turbine inlet.
