I agree 100% great turbo for a stock motor, I have twins on a 26/30 and have a collection of them from tdo5-16g,18g tdo6 20g & sl2. They make huge power, are easy to rebuild, cheap and responsive. I have seen the kinugawa turbo on a stock rb25 and it hammered, not sure if it was the one above or this one Turbo seat of my pants felt like 300+ rwkw it was on a high mount ebay manifold and ebay gate too cost him under a grand landed new a couple years ago.
