Are you sure about that? He said he's looking for 250-300hp, and the GTi-R isn't 250hp stock and the SR20 is a 2 litre..... The S15 uses a BB T28 (almost the same as the GTi-R one) and makes 250hp stock... But again, is the same SR20.
We're talking about an engine that's 400cc smaller as well... You'd have to seriously work the engine to pump the boost up to make that sort of power with that turbo, wouldn't you?
you dont understand what makes HP do you? CFM = HP, end of story.
yes its usually found on a 2 litre engine, which makes it IDEAL for a performance turbo on a 1.6. a 1.6 revs more than a 2 litre does. And being behind a 1.6 means you dont get instant boost like a PRODUCTION car does. std turbo's are sized for instant responce, low boost thresh hold low RPM torque etc which isn't what we want on a performance 4 cylinder is it? we want to rev it to 8000 and make power from 4-8000rpm
