I am not sure if there is a thread about this. I tried searching BUT nothing popped up. so I hope this would be helpful to others.

Only thing that sways my decision about W2A intercoolers is that. You would have to mount the reservoir, run the water lines, power lines for the pump, add a heat exchanger, add ice in it every time you take it out for a drive. But you get cooler intake air temps.

as for a A2A intercooler you just run the piping from the turbo outlet to the intercooler and to the intake with of course the BOV on there. less hassle and not mush weight you add. and all you would have to do is probably cut the bumper out and that's about it.

I was just seeing which would be better overall for a weekend/track car.

 

im gonna guess most people will say a2a. cheaper, easier to install, more practical for the street and still capable of making plenty of power.
