Factory timing belts on the \u003cstrong\u003e5S-FE\u003c\/strong\u003e endure continuous cyclic shear load, leading to tooth sheer, belt stretch, and delayed cam timing. Simultaneously, OEM water pump mechanical shaft seals fatigue from heat cycles, weeping coolant past the bearing assembly and triggering premature bearing seizure, coolant loss, and radial runout.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive overhaul kit features an HNBR-formulated high-tensile 163-tooth timing belt engineered to resist longitudinal stretching, oil contamination, and thermal cracking under high-RPM operation. Paired with a heavy-duty, direct-fit cast aluminum water pump equipped with precision-ground impellers and long-life mechanical shaft seals, the assembly delivers maximum fluid volumetric flow across the mid-ship cooling circuit. Premium sealed tensioner and idler bearings minimize frictional drag, while replacement Viton-grade camshaft and crankshaft front main seals stop oil contamination at the source.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Timing Belt (163 teeth)\u003c\/li\u003e\n  \u003cli\u003e1 Tensioner Roller Bearing\u003c\/li\u003e\n  \u003cli\u003e1 Idler Bearing\u003c\/li\u003e\n  \u003cli\u003e1 Crankshaft Seal\u003c\/li\u003e\n  \u003cli\u003e1 Camshaft Seal\u003c\/li\u003e\n  \u003cli\u003e1 Water Pump with gaskets\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: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\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;\"\u003e1991-1994 Toyota MR2\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;\"\u003e5S-FE \/ SW21\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;\"\u003e130 hp \/ 140 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\u003e1991-1994 Toyota MR2 Base \/ Coupe \/ T-Bar 2.2L (5S-FE DOHC 4-cylinder)\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 SW21 MR2?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1991-1994 Toyota MR2 equipped with the \u003cstrong\u003e5S-FE\u003c\/strong\u003e 2.2L or \u003cstrong\u003e3S-FE\u003c\/strong\u003e 2.0L DOHC 4-cylinder engine. \u003cstrong\u003eDoes not fit 3S-GTE Turbo models, V6 engine swaps, or 1.6L AW11 platforms.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to bleed the mid-engine cooling system after installing the water pump?\u003c\/h4\u003e\n\u003cp\u003eYes, the long coolant plumbing runs on the \u003cstrong\u003eSW21\u003c\/strong\u003e require complete radiator and heater-core air burping using service petcocks to prevent air pockets.\u003c\/p\u003e\n\n\u003ch3\u003eThe Toyota Caliber\u003c\/h3\u003e\n\u003cp\u003eMaintain proper mid-engine balance and crisp mechanical throttle response across the powerband by safeguarding your valvetrain with exact-pitch timing components and true OE-spec thermal management.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67545245548792,"sku":"DS-EVSCSLIZJ","price":71.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-water-pump-timing-belt-kit-for-toyota-mr2-1991-1994-2-2l-1.jpg?v=1790720260","url":"https:\/\/performancechiptuning.com\/fr\/products\/performance-water-pump-timing-belt-kit-for-toyota-mr2-1991-1994-2-2l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
