The clearance to the firewall is very close to what my cardboard pattern had indicated.
I didn't do anything yet to the firewall or insulation. The cam sensor and left valve cover touch the insulation but aren't pressing against the sheet metal.
The mods to the Mivec oil housing are quite tight to the insulation.
I'm thinking of making dropped engine brackets, try to drop the engine 15-25mm to see if this gives me a little bit more space.
I can envision the fan and shroud being an issue, a slight change in the drive shaft angles and oil pans, and a hard hydraulic line on the steering rack that will need to be 'adjusted'. Other than that, I can't think of what would be greatly impacted by this lower position. But then I've been up for 20hrs and my eyes can't focus anymore...
Here's the engine hanging in an engine bay that had been empty for almost 6 months.
