{"product_id":"lsj-stage-2-kit-1","title":"LSJ Stage 2 Kit","description":"The ZZPerformance ZZP LSJ Stage 2 Kit offers a straightforward path to upgrading your supercharged '05-07 Cobalt SS or '04+ Ion Redline. This kit is dyno-proven and designed with both performance and reliability as key objectives, providing the appropriate supporting modifications to allow for a supercharger pulley change and subsequent power increase. The included PCM programming is tailored to your selected pulley size, commanding a flat air-fuel ratio and making minor timing adjustments as needed.\n\nIncluded in the kit are a ZZP modular pulley hub, screws, a breather barb, and a ZZP modular aluminum pulley in your chosen size. You will also receive (4) NGK BKR7E spark plugs, (4) Siemen 60# injectors with di-electric grease, and an EV6 injector adapter harness. Depending on your selection, the kit will also include a ZZP Stage 2 belt, an Oversized (OS) tensioner pulley, or a ZZP adjustable tensioner, along with instructions for each part.\n\nThe kit offers flexibility in pulley and tensioner\/belt options. Pulley sizes include 3.1\" (recommended for 91 octane), 3.0\" (recommended with a ZZP downpipe and 93 octane), and 2.9\" (which recommends 60# injectors, a larger heat exchanger, dual pass endplate, header\/downpipe, and 93 octane). For tensioner\/belt options, the ZZP adjustable tensioner is highly recommended for its versatility. The ZZP Stage 2 belt is suitable for 3.1\" pulleys and can work with 3.0\" pulleys, but may lead to belt slippage with smaller pulleys due to reduced tension and grip. The Oversized tensioner pulley requires modification of the factory tensioner for clearance.\n\nThe 60# injectors included are capable of supporting up to approximately 375whp on pump gas, significantly exceeding the capacity of factory 33# or even upgraded 42# injectors. The kit also addresses PCM programming, offering options for a pre-programmed ECU, sending in your original PCM for flashing, or receiving a tune file if you possess HP Tuners. For those managing emissions testing, selecting a 'sending core' or 'email a file' option is crucial to ensure VIN compliance. Core charges are refundable within 30 days upon return of your original PCM core. Rental options for HP Tuners interfaces and laptops are also available for remote tuning, pre-configured for immediate use.","brand":"ZZPerformance","offers":[{"title":"Default Title","offer_id":52689675911480,"sku":"ZZP-LSJ-STAGE2","price":524.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687424124.webp?v=1784909046","url":"https:\/\/store.motormia.co\/products\/lsj-stage-2-kit-1","provider":"MOTORMIA","version":"1.0","type":"link"}
