It's official, a 2.3 4000 quattro is amazing....

I just bought a 5000CSTQ and drove it home (VT) from New Jersey. When I
first put my eyes on it I thought "what a watermelon on wheels". Well
once I got on the highway and gave it the gas I was sold on the Turbo
motor. It hauled butt all the way back and I got 30 miles to the gallon.
Now to my question. How can a 2.3 natural even come close to the power
a 2.3 turbo? My intention is to use this motor for my 4000Q swap and I
just want to make sure I'm not missing any better options. I have a 1990
80Q and it seems peppy but not that peppy. Thank you for your help.
