They didn't say it spooled by then, just that the power boost was noticable. Small motors like the 1.8 in the Miata take a while to build up the steam required to get a good kick in the pants from a turbo. I'm sure Mazda could've found a more suitable setup, but I'm guessing there was limited R&D funds available and they just slapped on what they know will work.
Come on, a smaller turbine housing would have been how much more difficult? I think the torque curve would be a lot more entertaining if the boost rose faster.
you sacrafice top end though, with a motor this small, the powerband is very narrow with the use of a turbo. Top end is more important in a car like this since it's marketed as being sporty. A *good* 1.8 turbo can be done, just look at VW/Audi's offerings,
however that Mazda motor wasn't designed from the ground up for turbo use I'm guessing, which makes getting it to work with a turbo tougher...
Edit - don't get me wrong, this could have been better executed, but Mazda *really* half-assed the turbo setup on the Protege, and I suspect the same happened here.
