You may notice a change in this picture from the previous two full frontal shots of Le Peu.

I spilled a little antifreeze.
oh yeah... and the car is on the ground! Running!

Next is a picture possibly best described as "shrinkage". Click for bigger ;)

This shows the serious difference in the intake systems between the two engines I've swapped. You're looking at the two different air filter box tops.
Smaller, more restrictive intakes generally make for better low end torque, but worse horsepower ratings.

One more pic after the jump, in which I believe you might see a difference w/o me describing anything.
