Safety First

Safety should always be your top priority when working on your vehicle. Here's what you need:

• Safety glasses and work gloves
• Jack stands rated for your vehicle's weight
• Wheel chocks
• Well-ventilated workspace
• Basic metric tool set

Make sure you have these supplies on hand:

• High-temperature RTV sealant
• NPT thread sealant
• Fresh engine oil and filter
• New exhaust manifold nuts (Recommended part numbers: Scion SU003-02873 or Subaru 902370010)
• Factory service manual for reference

Step 1: Vehicle Preparation

1. Disconnect the battery's negative terminal
2. Remove the front bumper assembly and under-covers
3. Remove the crash bar and washer fluid tank
4. Remove the factory exhaust manifold (Pro tip: Use penetrating fluid to make this easier)

1. Remove the oil pan and prepare for modification
2. Tap a 13mm hole for the turbo oil return
3. Install the provided oil return tube (welding required)
4. Set up the 3-way oil fitting system for turbo lubrication

1. Mount the turbo brackets and spacers
2. Install the new turbo manifold with supplied gaskets
3. Mount the turbocharger assembly
4. Connect all oil feed and return lines
5. Install the downpipe and test pipe assembly

1. Modify the front bumper support for intercooler clearance
2. Mount the intercooler using supplied brackets and spacers
3. Install all intercooler piping and secure with provided clamps
4. Connect the blow-off valve and ensure proper fitment

After completing the installation, several crucial steps remain:

1. Double-check all connections and fittings
2. Verify all sensors are properly connected
3. Ensure proper clearance between components
4. Professional tuning is strongly recommended

• Take photos before disconnecting any components
• Label all vacuum lines and electrical connections
• Organize hardware by step to avoid confusion
• Have a professional shop available for welding if needed
• Consider purchasing new OEM exhaust manifold nuts
• Plan for a professional tune after installation

To keep your newly turbocharged vehicle running optimally:
