{"product_id":"tte550-n55-upgrade-turbocharger","title":"TTE550 N55 Upgrade Turbocharger","description":"The The Turbo Engineers TTE550 is a performance upgrade turbocharger for the N55 engine, built to provide greater power and efficiency. This unit retains the original turbocharger housing but replaces the compressor wheel with a TTE milled aluminum wheel featuring state-of-the-art 7+7 blade geometry for increased power output. The original exhaust turbine is swapped for a larger, lightweight 9-blade TTE-designed turbine, which results in lower exhaust gas backpressure and improved performance, while still maintaining good spool response.\n\nDurability is enhanced through the integration of a TTE motorsport upgrade bearing system. The turbochargers undergo a rigorous balancing process: individual parts are balanced at slow speeds (up to 2800 RPM), and then the assembled CHRA is dynamically balanced at high speeds (up to 250,000 RPM) using an in-house VSR machine, exceeding OEM standards. Each turbocharger is supplied with a serial-numbered balance test result document.\n\nKey features include genuine housings and components, a highly efficient next-gen billet compressor geometry, optimized compressor cover machining clearances, and a genuine diverter valve. It offers fitment as original, plug-and-play installation, a TTE billet larger compressor wheel with a 56mm inlet, a TTE high-flow bigger turbine, and a motorsport bearing pack. The TTE550 is proven to handle up to 550 PS.\n\nSoftware recalibration is required after installation. This product is made in Germany and comes with a lifetime replacement program. Please note that any cancellations will incur a 5% refund fee. Additionally, this turbocharger is not for sale or use in California on any pollution-controlled vehicle as per the California Air Resources Board regulations.","brand":"The Turbo Engineers","offers":[{"title":"Default Title","offer_id":52663984947512,"sku":"TTE10074","price":4148.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687723152.jpg?v=1784331517","url":"https:\/\/store.motormia.co\/products\/tte550-n55-upgrade-turbocharger","provider":"MOTORMIA","version":"1.0","type":"link"}
