These little guys showed up today (Thank to Jeff Perrin!). I’m putting these in place of my stock R34 turbos in my 90 R32. These are the GT2860R ‘-5’s. [707160-5]. These flow enough for somewhere around 350 crank hp each, so I suspect you I can get 600whp out of them in twin in my setup with cams. I am sure they will be a delight to install.
