Civic Si vs Lexus IS300

Nice kill man, i havent really raced one, but i have heard mixed experiences. Many of my fellow tuners have slain the glitzy IS, but others have claimed that on the highway, they keep up pretty nice. If im not mistaken, they run the same engine you can find in a non tubo Supra. Does anyone know if its possible to put supra turbo kits on that engine? That would be interesting. (Along with some huge robot graphics on the side hahaha)
