Easier said than done, but it can be done. Getting just the motor is one thing, you will also need the harness, the ECU, and a whole bunch of little tidbits here and there.

Easier said than done. I heard there are problems with fitting a b4 engine into NA models due to the left/right driving and the location of the twin turbo. Do some research. It can be done but I hope you sh!t goldbricks

Good words of advice here. The best route is to just get the front clip off a B4. That way you have all the parts you "could" possibly need. The engine will fit into LHD cars though fitment will be really tight on the drivers side. For what it's worth, a WRX engine swap will be cheaper and easier to mantain than the TT setup the B4 has. Also if $$ is no object, wait a bit and consider getting the 2.5T engine and 6sp MT.
More thoughts, If you haven't got there yet. Putting that much motor in a car will require good brakes to stop and suspension to control the car. If your serious about the engine swap, I'd do those two items first.

Also, The B4 comes in various trims with the 2.5L and 2.0L and 2.0TT. So wanting a B4 in your wagon might not be that hard as if it's a GT you just need to rebadge it RS25:D

also to let you know
B4RSK motor is same as Legacy Touringwagon GT-B
B4RSK or GT-B' either it won't fit on US car without relocating the turbo.

B4RSK motor is twin turbo but it's not as powerful as WRX's single setup because it's a sequential twin turbo.
It has faster spool up than WRX's single set up but WRX's motor has a lot more punch than B4 TT. I'd go for WRX's motor instead of B4RSK-GT-B. More power, easier to swap.

No need to relocate a turbo, just need a custom uppipe. (maybe it was the downpipe, can't remember. But it was one of those.)

I did the swap on a LHD legacy and you will need to modify both up pipe and down pipe to clear the brake booster. And yes, it is really tight
