All complete. Finished pics will be up tomorrow.
Total cost in the end:
$0 2nd Plenum (Cheers Zuffen!) for the snout
$10 2nd TB postage (Cheers Edz!)
$90 Turbo bellmouths x2 (going inside air cleaner)
$130 Oval K&N Air Cleaner plus enough K&N foam to make 3 mud covers
$32 for a slab of boonies best for tigging
$70 10mm Aluminium to make base and top plates
$30 Linkages between TBs
Total cost $362 but if you minus the air cleaner (which we always spend mega $$$ on anyway, one of the joys of offroad) it works out to $232, and you could do it without the bellmouths if you wanted and save another $90.
Thanks heaps to Zuffen and Edz - massively appreciated!
