We are using the same formula, but you are using it incorrectly.  In the
Delorean's case, peak HP is 130 at 5500rpm.  The torque is 124ft-lbs at
5500rpm.  Likewise, at the peak torque, 153ft-lb@ 2750RPM, the horsepower
is 80HP.    It is rare to have peak torque and peak HP at the same RPM.

A properly turbocharged engine will make more torque than the same
non-turbocharged engine.  
Therefore a smaller engine that is turbocharged will make the same torque
as a larger, non turbocharged engine of the same type/technology.
A larger turbocharged engine will make more torque than a smaller
turbocharged engine.  

would you choose a diesel over a turbodiesel?
