I do know that I drive torque, while listening to my friends prattle on about horsepower.
Don't the g60 ic's have plastic end tanks? I'm not sure what kind of boost the g-grenades were putting out in stock form but if you plan on running big boost I personally would want an all alloy design.
The G60 intercooler (horizontally placed) is a direct fit. The G60 and the euro spec GTD intercoolers are the same, however, you'll have to relocate the power steering reservoir and change the cooling reservoir (if you don't have the round style one).When I installed that intercooler (from a GTD) I had everything from the donor car: intercooler, piping and brackets, but I decided to make myself the rear bracket to leave my old (and bigger) cooling fluid reservoir. If it's the IC from a Rallye (front, vertically placed) it can be installed easily as well.In any case, you'll need custom hoses if you don't have the GTD ones.
