Re. Sumps:
The Aussie sump are expensive, however, from what I've seen, they are considerably better then the US ones - probably the best fabricated ones there is. No idea whether there is more than one Aussie manufacturer, but check this link

for some pictures of one on a customer's conversion. The ground clearance is very good. Also, it had tubes welded in for access to the sump screws. Appologies for the ongoing problem with the picture galleries on my site - it's a software bug. If anyone's a NetObjects Fusion 8 expert, please help!
There is no way any 'wide' sump will fit with a smallcar type mount, as the mount limits the sump width to pretty much the standard dimension.
One of the German alloy sumps is also fitted to another customer's conversion. Check

The subaru mounts have had to be moved out sideways to make room for the sump, which was designed for Beetles. I doubt the 10 degree oil temp claims. My beetle didn't show any noticable drop in temp when I fitted an allot sump extension. I then fitted a 13 reo full flow cooler. This dropped 25 - 25 degrees c off the oil temp.
I'm working on a sump, but as most of you probably know, rather slowly. Appologies for that, but If I could get it done faster, I would.
