Its essentially the same thing. N80 = EVAP solenoid... The PCV plumbing and pipework is slightly different on the 3B from ABY but functionaly the same.
With a catch/cyclone tank you have two options in regards N80 -
1 - Blank it off
2 - Integrate it with plumbing to cyclone tank
Problem with 1 is that it prevents any pent up fuel vapour in the tank from being ingested by the engine - the ECU modulates N80 when off boost so as to allow any fumes (treated by carbon canister) to be sucked into inlet manifold.
Problem with 2 is the pain of extra pipework to accomodate the N80 output fumes to enter the cyclone tank - from where they can be vented back into engine or out to atmos if thats how you want it... Oil vapour will be caught of course, and returned to the sump - manually or otherwise !

Some details on removing the N80 and carbon canister are here.
I had to do this years ago, as my fuel tank was pressurising.SSComment

Actually - yeah - thats option #3 - just vent the tank fumes to atmos...
N80 needs to stay connected as Stu says.Paul Nugent

Just plug the hose that enters the IM, so you don't get a boost/vacuum leak. Leave the N80 pluged in or you'll get a fault code.
Then go to the boot and you'll see where the pipe exits the tank breather to go to the front of the car, disconnect that and replace it with a hose that will be the new vent. I routed mine out the air vent in the boot, so the fumes exit behind the rear bumper.
You can then remove the carbon canister and all associated unused piework.
Stand back and admire the less cluttered engine bay.
Best bit of advice
My S2 ran fine thanks to Stu's postChefComment
