LSXcalade Twin Turbo Engine Setup Details! Why Does it Work So Well? (Tips For Your Own Build)
What happens here
Mitchell describes his custom fabrication work, starting with the exhaust headers which he built himself. He notes that the original design conflicted with the larger valve covers required for the shaft rockers, leading to further modification. The engine is positioned slightly off-center in the engine bay from the factory, which added complexity to fitting components. The exhaust system features a 3.5-inch diameter, transitioning from stainless steel near the turbos to aluminum towards the rear for weight reduction. He also converted the throttle body to a drive-by-cable system, using a G-Plus throttle body from eBay with a custom sheet metal bracket for the throttle cable and a shaved alternator for clearance. The V-band flange was also welded on by him.
Goal: Explain the custom fabrication work, including headers and throttle body conversion, and the exhaust system design.
