Designed for builds chasing more power than the factory cast manifold can support while keeping bottom-mount turbo packaging.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Does\u003c\/h3\u003e\n\u003cp\u003eThe factory SR20DET cast iron manifold cracks. That's not a maybe, that's the reality on any SR that's seen real boost or heat cycles, especially the S13 Redtop and S14 Notchtop manifolds. The V3 tubular replacement uses Schedule 10 weld-el pipe sections, which is thicker than most aftermarket tubular manifolds on the market. Thicker wall thickness means better resistance to thermal cracking, longer service life under heat cycling, and the confidence to make real power without watching for cracks.\u003c\/p\u003e\n\n\u003cp\u003eThis is the upgrade over the ISR V2 manifold, with the V3 stepping up to Schedule 10 piping for serious builds. Bottom-mount design retains factory turbo positioning, which keeps things simple if you're using the stock T25\/T28 turbo or a direct bolt-on upgrade.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Note\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eOn some T25 or T28 stock turbos, you may need to clock the turbo slightly to clear the larger runners on this manifold.\u003c\/strong\u003e Plan for this during install.
