from what i hear the turbo is not under warrenty anyway, mabye thats bs but thats what i heard on another forum(it could be just for canada or you have to get the MAP, im not 100% sure)
i asked the shop foreman about a top mount intercooler and rear engine mount and he said it would be ok. i never said what brand, so mabye he thought it was mazdaspeed parts?
not a chance --- i was just at the dealer today and they do not have mazdaspeed motor mounts or TMIC available other than what came with the car
actually, they don't have much of anything but sport springs, cai, coilovers, and rims
