{"product_id":"stage-3-250cc-80-fuel-injectors","title":"Stage 3 250cc\/80% Fuel Injectors","description":"The Unlimited Diesel Performance Stage 3 Injectors are a set of eight remanufactured, hybrid-style fuel injectors engineered for 1994-2003 Ford Powerstroke 7.3L diesel engines. These injectors offer a 250cc capacity with 80% nozzles, designed to support up to 500 rear-wheel horsepower (RWHP) while also being tunable for towing heavy loads with sustained Exhaust Gas Temperatures (EGTs) below 1250°F. They are an excellent choice for those who have upgraded their turbocharger.\n\nEach injector is built with new tungsten-coated plunger and barrel assemblies, new nozzles, and includes replaced o-rings and new nozzle springs. The solenoids are inspected for proper resistance, and injector clearances are reset to proprietary specifications. These injectors are cleaned using a Pro Ultrasonics unit and bench-tested across a full range of RPMs and oil pressures.\n\nCustom tuning is required for optimal performance, particularly on all 1999-2003 model years, as these are single-shot injectors. The product also notes that for Early 99 trucks, drivability issues with tuning may arise, potentially requiring a conversion to a Late 99 PCM. While dual high-pressure oil pumps are not a requirement with proper tuning, head studs are recommended if planning for over 40 psi of boost, and fuel pressure should be maintained at or above 60 psi.\n\nUnlimited Diesel backs these injectors with a Limited Lifetime Warranty. The product description also details common issues that necessitate Powerstroke fuel injector replacement, such as plugged nozzles, scored plungers and barrels, broken springs, and worn armature clearances.","brand":"Unlimited Diesel Performance","offers":[{"title":"Default Title","offer_id":52860394996024,"sku":"UDP-7.3-250CC-STAGE3","price":2274.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687934291.jpg?v=1787767229","url":"https:\/\/store.motormia.co\/products\/stage-3-250cc-80-fuel-injectors","provider":"MOTORMIA","version":"1.0","type":"link"}
