{"product_id":"lsj-stage-2-kit-2","title":"LSJ Stage 2 Kit","description":"The ZZP LSJ Stage 2 Kit from ZZPerformance provides a straightforward path to upgrading your supercharged '05-07 Cobalt SS or '04+ Ion Redline. The included ECU is pre-programmed to maintain a stable Air\/Fuel ratio and optimize ignition timing in conjunction with pulley size reductions.\n\nIncluded in the kit are a ZZP modular pulley hub, your selected aluminum pulley (available in various sizes like 3.1\", 3.0\", and 2.9\"), and either a ZZP flashed ECU or programming support via HPTuners. You will also receive (4) NGK BKR7E spark plugs with a .035\" gap, (4) Siemen 60# injectors with necessary adapter harnesses, and your choice of a ZZP Stage 2 belt, an Oversized tensioner pulley, or a ZZP adjustable tensioner. Comprehensive instructions for each component are also provided.\n\nProper pulley selection is crucial: the 3.1\" pulley is recommended for 91 octane fuel, while the 3.0\" pulley requires 93 octane and a ZZP downpipe. For the 2.9\" pulley, 60# injectors are recommended, along with a larger heat exchanger, dual pass endplate, and header\/downpipe, all while running 93 octane. The tensioner\/belt option also impacts reliability; the adjustable tensioner is highly recommended for smaller pulleys, as the Stage 2 belt may experience slippage with pulleys smaller than 3.0\". The Oversized tensioner pulley requires modification of the factory tensioner.\n\nInstallation requires removing the stock supercharger pulley, for which a puller may be rented or purchased separately. The PCM portion of this kit is non-returnable. If your vehicle is subject to E-Check emissions testing, specific core charge options must be selected to ensure compliance, as the VIN cannot be altered on the flashed PCM. For those using HPTuners, ZZP can provide a modified file to upload yourself, or offer remote tuning services with a rented interface and laptop.","brand":"ZZP","offers":[{"title":"Default Title","offer_id":52867001975096,"sku":"ZZ-LSJ-STAGE2-KIT","price":749.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687423399.webp?v=1787910056","url":"https:\/\/store.motormia.co\/products\/lsj-stage-2-kit-2","provider":"MOTORMIA","version":"1.0","type":"link"}
