Description

The Treadstone M145 is a unique cast stainless turbo manifold specifically designed for the Lexus IS300 (2001-2005) and Supra 2JZ-GE engines. This manifold is investment cast from 304 stainless steel, offering a robust and durable solution for turbocharging these vehicles. It is engineered to accept any T4 tangential turbine housing and any 2-bolt wastegate. For those seeking to use a larger wastegate, an adapter for a 2-bolt to MVR44mm wastegate is available separately. Treadstone manifolds utilize advanced CAD techniques and an exclusive investment casting method with 347 stainless steel. This material provides high thermal inertia and excellent heat retention, maximizing the thermal energy delivered to the turbocharger for improved system efficiency compared to tubular manifolds. The 347 stainless steel construction also offers exceptional resistance to rust and corrosion, ensuring longevity and a lasting aesthetic. The manifold features an M10 X 1.25 thread pitch.
