Aluminium Sump for 4AGE. Good idea? Bad idea?

[Stealer Of Souls]

Hey.
Was think about some stuff yesterday and I wondered if anyone had come across or has an aluminium sump on their 4AGE.
Where could I get one (or get one made up)?
Is it a good idea or bad idea or just an idea?

I figure that it'd be okay on a road car, and perhaps on circuit cars as you're relatively unlikely to smash the sump against anything.

Oh yes. The idea.
Magnetic sump nuts. Seem rather limited in their pickup area, although the idea has some merit. Also I figure it must be a bit hard to clean them off.
So I thought why not have a aluminium sump which can have a couple of long bar shaped neodynium or samarian cobolt magnets strapped to it. Then at oil change time, you remove the magnets and the particles should get drained out with the oil. No fuss, no muss.
As a side benefit you could save a few grams in weight...

Yes you can get one in fact I have just bought one as part of a dry sump setup , they are made by TRD and I consider mine a bargan at $2500, as a second hand system.
Really if you want that ali look then go and buy yourself some silver paint and save yourself a whole lot of torture of getting one made.If you are worried about bits floating around in your oil the replace your filter with a decent one often

Also, why would you want an aluminium sump?
Surely the weight savings would be negligable, and what other reason would there be?

I was on that thread.
Welll... electromagnetism 101. A standard steel sump would "block" most of the magnetic field. Even from a very strong magnet. Aluminium is non-ferro so would have minimal effect of the magnet field produces by the magnets.
The benefit of this (as I see it) is that when you remove the magnets from the sump the bits of metal in the oil, which were previously held in place by magnetic field, are now free to drain with the oil. Any that don't will become held again when you replace the magnets after the oil change.
No magnets to try clean (neo magnets are really strong. It's quite hard to pluck small particles off them) and a great capturing surface (tip of sump plug vs long strip along the base of the sump).

The weight savings are probably 5/8s of SFA.
but if you apply mazdas gram approach. A gram is a gram.

There was also the fleeting thought of magically finding a cast aluminium sump with additional cooling fins for that extra hardcore 1 degree cooling oil temp...

the other question is, how much magnetic metal particles are you expecting to get in your 4age?
The link above discusses that pretty well

alloy sumps dissapate heat better...
My 7A came with a half alloy sump

But if you ever hit the aluminium sump into the road over a judder bar or something wouldn't it crack? (I'm thinking cast aluminium, maybe your thinking of using something else?)

Just asking this because I've never seen a sump yet which hasn't been hit on the road at some stage in its life.

thats why the top half is alloy on mine and the pan is tin :d

At my work we have had two EVO's in for rebuilds cos they are too low and have had their sumps crushed by driving over something. The pickup was blocked from the sump being crushed and it ran bigend bearings.

Yeah. True. But I am getting and engine re-conditioned at the moment. Should be lots of particles to pick up during the run in...

Would it matter then if the sump was alloy or steel or whatever?
But yeah. This is my biggest concern. If you whack an alloy sump it might just get ripped completely apart. Even with a relatively small hit...

That hits the nail on the head, i have a 6 litre sum on my 2JZ which i TIG'd up using 3mm aluminium sheet
