Tons of variables, too many to really be able to say with certainty. I'd guess at an upper limit of around 150-160 HP out of 1971cc with half-decent longevity... But it really is a guess.

Do you need to keep the stock 1971cc displacement? Do you need to keep the stock injection (and therefore the stock cam)? Are you talking about just bolting on external bits and going, or full-on rebuilds? Are you willing to lose all semblance of cabin heat? Are you willing to pop for super-grade fuel all the time, possibly with extra octane-enhancers added afterward? Are you willing to invest Big Bucks for all the "little" tricks that add half an HP or so? How long does the engine need to live??

If you're talking about keeping everything stock and just bolting on a few external parts, I'd guess you'd be stuck with less than 110 HP total.
