The new celicas are very light, lighter than us. We'd need a few bolt ons to stay even with the GT models even though their engine isn't terribly different from ours, the GT-S are tough to catch.

But, I've heard that Toyota is having some trouble with the GT-S engines, when they get up to their 8K rpm redline, the valves sometimes just drop into the cylinders. That would majorly suck.
