Tegs are not slow and heavy. They are just slow. Preludes on the other hand are slow and heavy.
An Integra is supposedly higher on the "food chain" of honda/acuras versus a civic hatchback, but hatches w/b16 or b18 engine swaps will consistently out-do a comparably modified integra, on the strip (and on a road course). That's only if you don't mind driving a civic hatchback, although I think the EK's can be made to look pretty nice.
