Interesting point...
... getting the power you have to the ground before worrying about how much power there actually is....
I've seen people with VW's take Hemi's in an 1/8 mile.
I've beat a turbo'd 5sp up to 100 miles per hour in my ... equqivalent automatic ... chrysler 2.2L turbo.
I've seen stock Buicks take Corvette's... anyone remember the GNx?
and now we have a 2.4L... I've seen 2.0L with 200 HP....
one thing to consider... put that subaru in a tug of war with your toyota...

need I say more?
