Supra 2JZ Ultra-Flow Intake Manifold with 90mm Throttle Body

The Speed Force Racing Supra 2JZ Ultra-Flow Intake Manifold is a critical component for achieving 1000 horsepower at the wheels, designed to efficiently deliver air into the engine. Extensive flow bench testing, verified by a Superflow 600, shows all runners flowing within 1% of each other. This intake manifold features a significantly larger plenum volume than competing designs, with a carefully sculpted shape that ensures near-perfect flow distribution to all six runners. Velocity stacks are integrated to maximize charge air velocity and airflow, making it capable of supporting over 1000 horsepower when combined with a billet 90mm throttle body. Constructed from 6061 aluminum and TIG welded with 4043 rod, the manifold's plenums are formed from a single piece for superior strength, avoiding the potential failure points of multi-piece designs under high boost. The intake manifold is hand-finished both internally and externally, pressure tested to 50 psi, and polished to a brilliant shine. The throttle cable is positioned to be hidden from view. This intake manifold features shorter runners to enhance top-end horsepower. It is compatible with Bosch style injectors, utilizing welded bosses rather than press-fit ones. Speed Force Racing offers this intake manifold with a choice of throttle body diameters, ranging from 75mm to 105mm.
