difrnt

Hi guys, been thinking about this for a while, but its not gonna happen any time soon. Has anyone ever replaced the standard engines with something a little more powerful? like say a v8 or turbo? I'm thinking about making a show car so it probly wont be registered. I know u can supercharge the standard motors, can u turbo them? Has anyone ever airbagged one? Also does anyone know of a tarago show car any where? i have lots of ideas for this one. Thanks Karl
