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 TubularTurbo 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 Flangeis 1/2"mild steel, and sanded Perfectly Flat before completion. All flange transition are Ported to Perfection. This unit is setup for an IWG T3 EFR turbocharger by default( T4 for those looking for over 450rwhp). We now use a Cast 3 into 1 merge collector for increased longevity. You must Premix. You cannot have a1700 degreeturbo manifold next to the Oil Metering Pump, as it will Burn Up as seen multiple times on competitors turbo systems. There isNothing WrongWith Premixingan Rx-8 engine, andIt Is Actually Better for the engine in the long run. The turbo manifold also requires trimming of the OEM passenger side motor mount bracket, and modifications to your radiator hoses/thermostat assembly as seen in our full kit. You cannot have a 1700 degree turbo manifold next to your rubber radiator hoses as seen on competitors turbo manifolds.
