Dug this up from the dead to give a few thoughts...

Did a VF39 install yesterday. Thanks for the pics and instructions, it went very easy with the guidance of this thread.

- Do not loosen/unbolt the turbo from uppipe until after you have taken off the coolant lines. I did, and ended up with some (not much) coolant running down into the uppipe. Not a big deal, but I would have avoided it if I had thought about it before hand (doh!).

- For some reason, when my TurboXS uppipe was installed by anonymous local vendor X, they double-gasketed the UP-Turbo (one old, one new :/). I used a single new gasket and torqued to 35lbs. No leaks.

- I found it easier to remove the hard oil line from the block and turbo than to bend it out of the way. I feared breaking it more than the difficulty of reinstalling it, which was a PITA and took quite awhile. If you have the time, I'd think about removing it entirely.

- My TD04 had washers on both sides of the banjo bolts, so I reassembled the same way.

- Before tightening the turbo onto the uppipe, reinstall the passenger side TMIC bracket. It's a PITA to tighten the bracket bolt that is underneath of the coldside outlet once the turbo is fastened down.

- Both of my coolant lines leaked at the turbo after reinstall. The hoses are older and have 47k miles on them, so replacing them may have solved the problem. I took the easy route and hose-clamped both lines on the turbo side, done deal.

- I bought new vacuum-lines/T/pill from Subaru and used Zip-Ties on the inline coupler where it connects to the factory BCS to ensure I didn't have any boost control issues on the plumbing side.

- This might be just my mind playing tricks on me: The coldside outlet appears to be slightly offset of my TD04, which made the passenger side of my OEM TMIC sit closer to the firewall on that side, and miss the bracket. I pushed the IC hose further onto the pass side y-pipe deal and it fits fine now.

Good luck to all!

EDIT: My swap was on a 2L, so a few things might be slightly different.
