Its restrictive runner profiles, rough internal casting, and lack of a turbocharger mounting flange make forced induction impossible without custom fabrication. In addition, stock cast assemblies are prone to thermal fatigue, excess weight, and high exhaust reversion when backpressure builds under aggressive driving cycles.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed with mandrel-bent stainless steel primaries, this tubular turbo manifold optimizes exhaust gas momentum directly into the turbine housing. Smooth internal transitions preserve kinetic pulse energy to accelerate turbine spool on the \u003cstrong\u003eB6ZE\u003c\/strong\u003e 1.6L powerplant. Precision TIG welds resist thermal cycling, elevated exhaust gas temperatures (EGTs), and structural stress under boost, while the standard T2 footprint accommodates compact T25 and T28 turbochargers for linear, responsive torque delivery.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x Stainless Steel Turbo Manifold (T2 \/ T25 \/ T28 Flange)\u003c\/li\u003e\n  \u003cli\u003e1x Exhaust Manifold Cylinder Head Gasket\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100% style=\" border-collapse: collapse border: solid font-size: min-width:\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e1990-1993 Mazda MX-5 Miata\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eB6ZE (1.6L DOHC) \/ NA\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e116 hp \/ 100 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1990-1993 Mazda MX-5 Miata Base Convertible 2-Door (1.6L L4 Gas)\u003c\/li\u003e\n  \u003cli\u003e1991 Mazda MX-5 Miata Special Edition Convertible 2-Door (1.6L L4 Gas)\u003c\/li\u003e\n  \u003cli\u003e1993 Mazda MX-5 Miata LE Convertible 2-Door (1.6L L4 Gas)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the NA MX-5 Miata?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1990-1993 Mazda MX-5 Miata equipped with the \u003cstrong\u003eB6ZE\u003c\/strong\u003e 1.6L engine. \u003cstrong\u003eIt does not fit 1.8L (BP) engines or 1994+ Miata chassis due to differing exhaust port spacing.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eIs an ECU tune required after installing this manifold and a turbocharger?\u003c\/h4\u003e\n\u003cp\u003eYes, any forced-induction conversion requires custom fuel mapping and ignition timing calibration to prevent catastrophic engine detonation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Mazda Performance Standard\u003c\/h3\u003e\n\u003cp\u003eDelivering true JDM sports car capability requires balancing lightweight responsiveness with thermal durability, ensuring your boosted roadster pulls cleanly through redline without manifold cracking or flow restriction.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67612796748024,"sku":"DS-EXWPFW153","price":407.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/stainless-turbo-manifold-for-mazda-mx-5-miata-1990-1993-1-6l-1.jpg?v=1791607622","url":"https:\/\/performancechiptuning.com\/fr\/products\/stainless-turbo-manifold-for-mazda-mx-5-miata-1990-1993-1-6l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
