Torque Solution Port Matched Oil Drain Flange - 10AN for T3 T4 T6 Small / Mid Frame Turbos

When you're setting up a custom turbo system, especially one using T3, T4, or T6 small to mid-frame turbos, getting the oil drain line right is crucial for keeping your turbo happy and healthy. This port-matched oil drain flange from Torque Solution makes that connection straightforward. It's designed to bolt directly to your turbo's oil drain port, providing a clean and secure 10AN fitting for your oil return line.

This flange is well-built with a focus on a good seal and proper flow. The port matching means the inside diameter of the flange is smoothed out to match the turbo's drain opening, helping to ensure oil can exit the turbo freely without obstruction. This is important because a restricted oil drain can lead to oil backing up in the turbo, causing seal damage and eventual failure. The 10AN size is a popular choice for turbo oil drains, offering a good balance of flow capacity and ease of plumbing.

Getting this flange installed is typically a simple bolt-on process, assuming your turbo has the standard oil drain flange bolt pattern. You'll want to ensure you have the correct gasket or sealant for the connection between the flange and the turbo housing, and then connect your 10AN oil drain hose to the fitting. It's a small but important piece for any custom turbo build.
