I'm jealous. I've been looking around for a 2.0 diesel to swap into a newer chassis Escort Wagon.

Of course, if I never find one, I'll probably end up doing a 3.0 or 3.2 swap into it.

Some pics of your car would help greatly, but going from memory, smoothing the area between the chrome front bumper and the hood's tip should help out some, while also creating a grille block for you. After that, add a chin scoop to pick up air from under the bumper for the radiator.

I'm not positive about the angle of the rear windows/hatch, so I can't comment there until I look into it more.

A belly pan is an obvious one, as well.

Dunno how you feel about overinflation, but max-sidewall is always an option, and will help out greatly if the max spec is much different from your current practice.

Of course, there is always the option to lower the Escort, as well.

Not that it would help much, but 155 R13's are slightly smaller tread width than your current tires. (10mm, about 3/8")
