I think that after 1997, or '98, they switched from a belt/noninterference engine to a chain/interference.
I have the original clutch in my '93 Corolla. No problems at all, nearing 160k.
And the car still averages higher mpg than the EPA estimate for the current Civic model, at least in the summer.
Also, being "blown away" by the power is a relative perception. From a 1.8 4-cylinder, he might have been expecting to move like a piddling snail, and been pleasantly surprised that it can in fact zip around rather quickly. No one should expect it to move like a Corvette or a Ferrari, and I see little point in timing a 0-60 run in a Corolla. How is that relevant to the car's purpose?
