Pretty much.
That unassuming sedan has about 150 HP, a close ratio 5 speed transaxle in the rear, DeDion rear suspension, inboard rear disc brakes, mechanical fuel injection, torsion bar front suspension. 50/50 weight distribution.
Engine is a 2.0 liter DOHC crossflow hemi. All aluminum with steel cylinders.
I modded it also. Poly bushings, big sway bars, Koni shocks, 11mm cams, header, lightened flywheel etc. Bumpers removed and body shaved to remove any evidence of those 75 pound weights at each end!!
