I was wondering if a few of you guys can give me some help. I am considering changing my k03 turbos to k04s and want to know what else I "have " to do to run these properly. I have read that I should replace the Intercoolers, replace the injectors, the MAF, the clutch as stock only holds 370bhp etc... Can someone clarify for me if I just change the turbos do i run a risk of damaging anything else. Is this even a good thing to do. I currenltey am running a stage 2( chip and borla exhaust). Any help would be muchly appreciated!
