this would be pretty much a waste of time and money especialy if you live in a hot part of aus.
the reason you would buy a GTR cooler and get custom pipeing is because of flow and cooling efeciancy. cheap kits are cheap kits. they dont flow, boost will drop and cooling is average.
also the cheap kits fit pretty average and most of the time the front bar has to be hacked to fit it where as GTR ones are made to fit.
