should be stock power...ish
i dont see why you would have more power, although the hybrids would be far more effecient... although i dont think it has that big of an impact at stock boost levels.

I'd think increasing turbo size keeping maximum boost constant should have the following effects:
(1) at a given boost level it'll flow more mass air than the stock turbo (so more hp at that point);
(2) it should be able to sustain maximum boost over a larger rpm range (higher rpm's), so maximum hp should increase;
(3) it'll take longer to spool than the stock unit.
Depending upon turbo size, it may make the car quicker or slower. Once you start dialing in higher boost is where you'll see advantages.

How does the factory ecu limit boost?
Does it set a maximum boost which is constant over all rpm's? Does it use some kind of maximum boost profile which changes with rpm's? Does it do the above but using mass air flow instead of boost?
I know that maximum boost is decreased in cold weather so I'm guessing it must incorporate mass air somehow into the limits it imposes.
