we have a '99 echo 1.5 vvti. it goes okay, but its a pretty big engine. they dont put out a lot of power but id say they are quite reliable. if you could fit one of these why not try fit the VTEC, i dont think they are that different in size. (the 1.5 that is).
or go the 1.3 k3-VE from a Sirion GTVI. they go pretty well and are a bit smaller. or import a 1.3 K3-VET (turbo). The UK also has awd versions of the sirion.. theres lots of variations to try

I wouldnt touch an echo. If you want something small and potent, with a bit of a difference id prob try the Daihatsu stable as suggested above.
If not the sirion any of the charade motors with a turbo on the side go quite nicely!
