Hi all. Deciding between the VTT GC 2.0 and the MMP cast 1k. They are approx. the same price. It seems the MMP have the same turbo that is on the stage 3, but with the added cast manifolds. Both twin sets seem great. I am looking for ~600hp or as much as I can get without adding PI yet. The reason I am upgrading is I need to do my oil pan gasket and my turbos have wicked rattle. I haven't been able to find much of any info on people installing and running the MMP1k. I did read the reasons why PR just went with the GC 2.0s and they do make sense.
