wait the edelbrock site claims their garrett turbo is ball bearing as well. they also claim 60% power gains at only 7 psi. Is greddy or apex'i(if i can still find one somewhere) gonna get me these gains with comparable spending (~3500$)? I will also be buying the kit for the d16z6 if I do buy one from edelbrock and there kit for the d16y8 has been out for almost a year now...isn't that enogh time(+ the r&D time on the z6 kit) to get the bugs out?
