Battery relocated and turbo intake pipe figured out.
Cut the headlight buckets out of the core support. Also had to cut off some of the top of the driver's side frame rail to make room to angle the battery under the top of the core support. New battery tray base is made of angle iron welded to both sides of frame rail. Made a tray that is tacked to that angle iron base. Made a mock battery box out of plywood to ease fitting and figuring the fabrication.
Had to abandon the rubber turbo inlet hose set up that I previously mocked up on engine stand. It conflicted with the master cylinder/booster. Instead, welded up some 3" exhaust bends. Top of airbox and inlet pipe are one piece, the pipe slipped over the box' barb and is RTV'd to that big airbox barb. Airbox is then fed through power module. BOV connects to bottom of turbo inlet pipe.
