Took a while Perry!!

Those alloy sumps, are they easy to get hold of? Do they raise up for exhaust clearance towards the back of the engine (flywheel end)? I am sick of having sumps weeping oil slightly here and there. Just though the alloy with a decent rubber gasket would be a better option.

Top inter cooler looks a little bit restrictive due to the U turn the top inlet is having to make but at supersonic air speeds it might not be that detrimental. I'd go for the bottom one if possible for this reason.
