lic adjustable timing idlers

LIC is now offering adjustable (eccentric) timing idlers; they've been in use on their own motor builds and current race car for quite some time. These used to be made in house by hand but now are precision CNC machined. These come engraved with LIC on the face, feature strict OEM tolerances, and have a 10mm hex for your socket to hold it in place while you adjust the timing with perfection. Current offering has been tested and proven on the LIC Motorsports Time Attack STi during the 2010 race season.
These especially play a role with heads and/or blocks that have been resurfaced, as well as different thickness head gaskets. These are recommended for any race build you do on a Subaru.

How it all works:
Idler #1: This upper idler when adjusted effects the RIGHT (Passenger side) intake/exhaust cams.
Idler #2: This lower idler when adjusted effects the LEFT (Driver side) intake/exhaust cams.
These parts are designed for longblocks that have been narrowed down from resurfacing the heads during a rebuild or decking the block and/or both. When that process is done it effectively retards the timing, this is because the belt has not changed length and something needs to make up that difference in the slack (the tensioner can only do so much); in a perfect world we would have different length belts to accommodate this. And some will say that's a good reason to use a different thickness headgaskets but its typically never quite close enough.

Likewise if you have different thickness headgaskets, these are perfect in conjunction with that, as the same issue is present (just vice versa, which is a lengthened block). This is what the LIC Motorsports adjustable timing idlers were designed around/for. Although they could be used to advance timing on a OEM spec motor, we only recommend them to bring your cams back into proper alignment.
