i've just ripped my ABS off my S2, didn't take to long but i have got the car on stands at the mo, the drivers side module and mounting plate is not to bad just undo the bolts that go in to the gear box, remember to put them back
its the pass side with the short shaft thats the 5HIT no room and hard to get to the mounting plate bolts, is alot easyer to pop the shaft to get it all off
as for pipes you will see there is another mount for the 4 pipes at the bottom of the bulk head, look for the pipe for each side that goes to a T piece on the inner wings, and form the mount for the 4 pipes follow it back to the master cylinder, then you just make up new pipes and go from master C to the T piece

you will need an XR3i fluid reservoir, or blank off the 2 plaky pipe on your one

hope this helps
