He don't drive on runway 365 days a year.

Yes 364 days on street and 1 day on airfield. BUT like i said i dont drive over 150mph on street and from that speed stock brakes are even better. Stock T4 200hp from factory hits maximum 146mph maximum speed by the way. :D

Or possibly a new oil drain.

Yes it will be both. Extra oil drain which works also as a breather. There will be also new aluminium 1.5liter breather box to stock place, but that later. :) Breathing system is okay with s60r box to 0-280km/h acceleration and after 7000rpm on 5.gear breathing system is pushing little bit of oil out so thats why improvements are required. :)

If it's going to be for drain back, it really needs to be below the level of the oil, that's why the stock one goes to the bottom of the oil pan - to prevent any potential CC pressure from inhibiting drain back.... Have you tested a drain port in this location previously?
