Grant, I do not have any experience with the Bekkers
motors, but I do have some biased insight:

1)  Its a 3.2L  with dual mode single vanos. Normally
    Aspirated.  Sure it has 330 hp, but how
    much more torque do you think it actually has
    over the stock 3.2L ?  My conjecture is not much.
    Probably no more that 270 lb-ft.  Is it very 
    peaky torque?  The stock 3.2L peaks at what...
    around 4Krpm?

2)  A Euro motor, which costs less, has 321 hp, but
    more importantly, has 258 lb-ft of torque, 
    and with dual infinitely variable vanos, 
    peaks at 3250 rpm, and has no less than something 
    like 240lb-ft from 2200 rpm or something.
    Betcha the Euro motor is more "usable" than the
    Bekkers motor.  

3)  There is no comparison between either of these
    motors and a turbocharged motor.  An Active stage
    2 has about 420 hp, sure, but its torque that
    accelerates.  The turbo motor pumps out over
    400 lb-ft of torque.  That's a lot of torque.
    That's a lot of instantaneous acceleration.
    However, the turbo motor will cost more, not cause
    the motor costs a lot more, but because the
    excess torque will break your diff, wear this out,
    wear that out....etc.
