I actually have a VF35 sitting around LOL... I like the turbo alot, it spools just a tad slower than a TD04, provides incredibly smooth power, and pulls good through the RPM range. It's my favorite daily driver turbo (currently). However, I'm just too curious about the upgraded 19T TD04, especially since it should spool at a lower RPM than the VF35 and flow more. My only concern would be the smaller hot-side for top-end, but time will tell.
