its not called a 7afte, casue the turbos were added by TMCA after the cars were built.
while doing that you could go one step further:
20v head, 4agze pistons.....
theres an easy 250hp, and the torque....
i imagne the would have cost a bit, take a topline corolla, add a 5k turbo kit and other extras, add profit margin.......
