The G5 is the GT2554R which is basically the same as the G6 with a very slightly smaller compressor wheel than the GT2560R. I would love to get new turbos AND do 2.5" piping/intercoolers but not sure the budget is going to allow that to happen all at once. But maybe if I go with just the G6 or G6X CHRAs it will leave me with enough $$ to get a head start.
