Basically in a nutshell it will cost you about another grand for the single turbo setup (depending on the initial purchase price of the cut/engine package) because of different dump pipes and crossmembers etc, but will repay itself ten-fold once you incorporate the maintenance side. Gen 3 TT motors are renowned for doing big end bearings, which means full rebuild time. Not cheap. Mine went through 3 motors before I got sick of it and dropped an STi motor in. No problems since.
Not only that, but you will not get away with 5k even with a B4 engine swap, unless you do ALL the work yourself, including splicing looms etc. Even then its a bit iffy. Budget minimum 6. And with a B4 swap, you need to incorporate tuning costs, because you will do a big end if you dont.
Some food for thought. Cost me 8900 to do my conversion from B4 to 2004 STi spec C motor. Included new alarm and new clutch, loom work, new 3" dump, everything. Drive in, drive out.
Power is doubled in the low range (talking 90kw at 2900 revs), and I am not below 170kw from 4500 revs now. I topped out at 155 (@ 6700 revs) after a tune with the twins. Power is smoother, and is a hell of a lot nicer to drive, and just to top it off, I get better fuel economy, and a motor that has done about 80 thousand k.
Basically, its chalk and cheese. Do it once, and do it properly.
