In short - none of it works or can be made to easily.
The spraybar is the easiest to setup you just need to connect the bar to the windscreen washer pump. However the nozzles are very poor quality, you'll run out of fluid very quickly and unless you carry about 25 litres of fluid it won't make any difference to performance of the chargecooler. Also if there is any alcohol in the fluid you use (there will be typically) then this will start to corrode the chargecooler rad fins if used for any significant length of time.
As for the Antilag and the Water Injection, there are cheaper, easier ways to do this rather than use the WRC parts. An aftermarket ECU and water injection kit will sort you out. One other point is that engines and turbo's never seem to last long when running antilag so expect frequent large repair bills.
Hope that helps!
