well I think I would go with the Corolla S and get a TRD supercharger.. and do all the suspension work, etc by yourself..
With the XRS you only get 127 ftlbs of torque but I believe that with the TRD supercharget you can easily surcome that figure..
Figures from website:
Peak torque is 145 lb.-ft. supercharged @ 4000 RPM
- vs. 125 lb.-ft. stock at 4200 RPM.
• Peak horsepower is 166 HP supercharged @ 6800 RPM
- vs. 130 HP @ 6000 RPM.
• Maximum HP gain @ 6750 RPM = +40HP
• Maximum torque gain @ 4000 RPM = +38 ft.lb.
so you loose 4 hp. and you gain 15 ft lbs.. I would rather have the extra 15 lbs
