{"product_id":"w-3-turbo-upgrade-1","title":"W.3 Turbo Upgrade","description":"The Weistec W.3 Turbo Upgrade is a performance enhancement for the BMW S55 engine, offering a substantial increase in power while maintaining a stock appearance. This upgrade requires your factory turbochargers to be sent to Weistec for a core process. Upon receipt, the turbochargers are disassembled, inspected, and then machined to accommodate a new 5-axis CNC-machined impeller wheel.\n\nExternally, the turbochargers remain unchanged, preserving their original look. The units are then reassembled with new seals and dynamically balanced for optimal operation and longevity, ensuring an OEM service life. Installation is straightforward, as all original oil and coolant lines are compatible and bolt directly on. For those who wish to avoid downtime, a core exchange option is available where upgraded turbochargers are shipped first, contingent on the return and inspection of your factory units.\n\nThis upgrade unlocks the true potential of the 3.0L Twin Turbo engine, delivering significant horsepower and torque gains, particularly in the upper RPM range. For maximum performance, a Weistec W.3 Turbo Specific ECU Upgrade is recommended. Supporting modifications such as Weistec downpipes, upgraded spark plugs, and an ECU calibration are also advised for optimal results. Please note that this product is not street legal in all US states and requires your turbos and inlets to be sent to Weistec. Orders typically ship within 2-4 weeks.","brand":"Weistec Engineering","offers":[{"title":"Default Title","offer_id":52664118772024,"sku":"01-555-01859-9","price":3899.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687540478.jpg?v=1784333543","url":"https:\/\/store.motormia.co\/products\/w-3-turbo-upgrade-1","provider":"MOTORMIA","version":"1.0","type":"link"}
