I think it really depends on what you want to do with your car. Hell, you can roll with a DX in autox if you are a good driver and you work the suspension. Drag, that you'd need a better engine if you want to dominate on the street. To rule the drag you'd need a better engine, H22 (Prelude) ... But just think, if you don't buy a new engine you won't have to spend the extra cash for it.
Or you can just pimp out your ride and put a $7000 stearo/tv/dvd/game concole system in your custom interior ride.
