Well, the question I'd ask.. or questions, would be what's your horsepower at right now? And what do you plan on doing in the future? ( Ex: Upping the boost, building the motor, etc. ) Most intercoolers are rated at horsepower levels.. so I'd pick the one that suits your power goals. You don't want one that's too small now, do ya?
An intercooler would definetly help you, as to what size is your choice on how much you want the air cooled. Don't get one too small though, you want to keep pressure loss to a minimum.
