heat soak

I've been getting ever increasing heat soak with climing temperatures over the past couple of months. Im considering a new intercooler, induction(pod etc..) and exhaust. In regards to the intercooler im stumped as to whether i should fit a top mount or front mount cooler. I'm told that a front mount will be much more beneficial for performance but will cost me close to three times more than a top mount. its basically the difference of $500 as opposed to $1500 and i guess it comes down to whether its worth spending the extra for what im guessing will be a minimal gain. Sorry for my stupidity but i prefer to come to you guys as your explanations are simplified for mechanicly void brains like myself also, are front strut braces(which are quite cheap)beneficial and easy to fit?
