To achieve my ~300awhp goal, I needed to swap out my turbo once again. The VF52 was a great turbo but was not getting me near my power goals on pump gas. The turbo runs really smooth, the spool up time is only 300 rpms later. It has better punch mid to top but has no low end power, which is only natural with a bigger turbo. The fitment was pretty tight and has slight issues. It was easier to get the inlet tube on if you have the intake manifold off. Good Turbo, tough fitment. Basically a newer Cobb turbo they offer, same specs.
