The IAG tensioner adds an additional roller like the tensioner used on factory WRC cars to help damp belt movement around the tensioner pulley. If you rev high, have a dog-type transmission, or use no lift to shift in your ECU this part is highly recommended.
The IAG tensioner comes with a billet bracket for additional rigidity.
The oil feed lines for the AVCS system are installed.
Next, the base for the front cover is installed.
All of the timing belt idler pulleys are installed.
Now our IAG Belt Tensioner is fully installed.

Great build, can’t wait to see her spinning on the dyno with those cam covers.
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.
We did a story on how the screens can cause problems. https://motoiq.com/the-dreaded-subaru-p0011-and-p0021-dtc-codes-dont-let-them-wreck-your-turbo/
I take it the heads are bench shimmed for valve clearance prior to being fitted ?
No shims, select fit cam followers.
Hey do you guys build engines an send to customers?
I suggest contacting IAG by following the links in the article.
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!
