Which turbo do you guys think has a faster spool up time, for a big turbo, a Turbonetics turbocharger to3/to4 hybrid with all the goodies, like ceramic ball bearing, basically the best to3/to4 turbonetics turbo you can get. Or the Garrett GT28r. It says that the GT28r is a dual ball bearing turbocharger, and I heard that dual ball bearing turbos are worse than a single ball bearing, like the turbonetics. This turbo would be for my '04 1.8t manual, all insight would be much apreciated
