UPDATE: Since I have been getting a constant flow of questions reguarding vr6 swaps into mk3s I'll add some advice and a parts list
First and foremost, Know what your getting into before you start this swap. If you dont even know how to change your oil thent his prob isnt for you. Though the swap is completly plug and play it takes a little bit of knowledge and a good sense of general mechanics.
The best advice i can give you is to search on vortex. Pretty much every question you have some else has already asked and some else has answered it. This was my first motor swap and before starting it I really knew very little about doing one, but lets just say i spent alot of time searching through archived links and talking to as many people as possible.
Parts list: Might not be 100% complete
Vr6 throttle cable
vr6 tranny (no your 8v tranny wont work)
vr6 Shifting Linkage
vr6 wiring harness
Correct ecu for the motor
vr6 Clutch master cylinder
vr6 clutch kit and flywheel
vr6 Exhaust manifold
Vr6 radiator and fan setup
vr6 Gauge Cluster
Some good info:
I would recommend replacing as many parts as possible while doing the swap. Dont do the swap if you dont have any money. Expect to run into problems. Parts that i would recommend replacing when you do it are parts that are easier to replace while the motor is out. IE: Clutch, Waterpump, Timing chains, Acc pulley, Crank seal, Oil cooler gasket, Crack pipe if its in bad condition, and any other seals/gaskets.
When i did my swap i replaced the following parts for good measure:
Motor mounts (black forest Stage II kit)
Upgraded clutch kit
Clutch master cylinder
Checked timing chains (found that previous owner replaced them)
Some other tid bits of information.
Parts that dont need to be changed if you dont want
-Axels (if your staying 4 lug)
-Suspension (2.0 stuff will work but vr6 is stiffer)
-Pedal Cluster (Same cluster)-Only needs to be changed for mk2 vr swap.
-Brakes(can remain the same, or upgrade to corrado rotors with vr6 calipers)
-To hook up the MAF: you need the vr cluster, the maf wiper stalk and the maf wiring harness. the harness hooks up from the stalk to the fusebox
UPDATED WITH MORE INFO:
Figured i would through this in here. In regards to the clutch pedal.. You do not need to replace it when doing the swap. The part number (1h1 721 321 a) is the same for both 2.0 and vr6. The pedal was designed to work for both. The clutch cable on an aba motor attaches to the top of the pedal. When doing the swap just remove the clutch cable and install the clutch master cylinder. The operating rod that sticks through the firewall to the inside of the car uses a clip in order to secure into the middle of the pedal.
The pedal for reference
The more you replace the better...Vw put alot of these upgraded parts on the vr6's for a reason so if you have the money do it right.
And heres the pictures
