I've thought about a S/C. I've actually designed a few prototypes that I think would be the cat's a$$. But, as I'm just getiing into the turbo field, I would rather start off small and follow a proven game plan.
You see, I also have a '93 Impreza that has a 2.5 RS motor swapped in. I've rallied that, and it's fun. It's been PnP'd, re-ground cams, and it puts out 150WHP, 158WTQ.
I've read about people putting out 200 CHP with only 5psi on a 1.8. Unfortunately, I have yet to see a dyno sheet proving this. But, if it's attainable at 5-7 psi, what could you get at 12-18 psi, assuming the block could take it?
