just finsihed doing this conversion. not to expensive when u do it ur self. bolt on turbo to RB25DE i have herd good reports about but u cant run much over 10 psi. its a pretty straight forward conversion so give it ago and dont worry wat other ppl say bout wasting money, its all about learning. Wack in the DET and run 15 psi thru it. im sure ull have a smile on ya face.
