So I rotated the battery 90 degrees, coz I couldn't get the cover off the fuse box as I had mountede it. Now I have heaps of room all round, ant the + terminal is nice and clear of everything.
Pics another time.
I made
this on the weekend :

Out of Bunnings poly pipe fittings.
With a bit of ridge removal, it's pretty smooth inside :

And fitted it tonight. It's a perfect size to adapt the ~70mm AW11 intake to the ~80mm blacktop plumbing.
I used the stub where the AW11 intake resonator used to go to mount the inlet air temp sensor :

And the final result is this (ignore random hoses laying over engine) :

So that's the intake done. 2 vacuum hoses to fit (cruise and a/c idle-up), and all the air / vacuum will be finished. Engine lid latch next.
I would have got more done, but spent all day sunday fitting a 2nd hand 4AT into a friends AE82, after she blew it up on friday.
Tonight, her auto died! It was fine test driving yesterday, after the engine swap.
I towed her home behind the trusty van, which didn't miss a beat, as usual.
