Turblown Engineering EFR IWG Rx-8 Turbo Manifold Combo

Please note we do NOT sell the turbo manifold by itself anymore, if you do not want a full turbo system, you can buy this turbo manifold + turbo combination.  Turblown Top Mount Turblown Manifold for your 2003-2011 Mazda Rx-8. This T4 3 into 1 Tubular Turbo Manifold Out Performs Log Style Turbo Manifolds not just in Peak Power, but Power Under the Curve, and Boost Response. Back to back dyno testing has shown a 1700RPM Difference in Boost Threshold, and a 40rwhp difference between a log manifold and the Turblown Rx-8 Turbo Manifold( @ 15psi, near 400rwhp).  The turbo manifold is constructed of Schedule 10 1.5" Cast Pipe( .110" wall). This is the Proper Size for an Rx-8 turbo manifold, as any larger, as found on competitor's turbo manifolds, will only increase lag considerably while adding no additional power. The turbo manifold and down-pipe have a Lifetime Warranty against cracks; if unmodified. The Engine Flange is 1/2" mild steel, and sanded Perfectly Flat before completion. All fla
