I'm actually flying to Germany at the end of the week for a friends wedding, so I'm just going to order all the parts over there, much cheaper than Australia.

So far I've got:
1. New intake pipes, turbo->intercooler, and 2x joints from intercooler -> intake. These don't seem to exist anywhere in Australia for purchase.

€142.00, LLS brand, apparently German.

2. New Elring Vacuum pump seal

€8.57

3. New Elring valve cover gasket,

€23.20

I guess it will also be a good opportunity to do the vacuum lines, I've had a few lengths of it sitting in the garage for a while now. Anything else I should tackle while I'm in there with a lot off the engine?
