Project GD Subaru STI, Building the Engine Part Five: Final Engine Assembly With IAG.

All of the front-end parts are torqued to the correct tightness.

The AVCS and exhaust cam pullies are installed.

The pullies are held with a special tool while they are being torqued down.

The Gates Racing timing belt is installed and the cam timing set by lining up all of the marks. The Gates belt is a higher spec than the OEM belt.  It is 300% stronger with 3x the heat resistance.

The factory belt guides at the intake AVCS cam sprockets are installed with a plastic shim to set clearance.

The guides are also installed on the exhaust cam sprocket.

  1. I assume for the AVCS oil feed lines, the factory style screens are not used right? I only thought about that because the style of banjo fittings used have the bump on top, which for Subaru means they put a filter in there.
    I’ve always wondered how dirty the inside of the cam covers get over time.

  2. When do we finally get to see this bad boy on the dyno? What intake, what turbo, what exhaust, what blow off valve, what header? This is 5 months old!
