The Honda Prelude never came from the factory turbo charged - so I'm assuming if he's modified it to the extent it is turbocharged - I'm assuming it has a host of other mods as well. THe STi is not the see all and end all of performance cars. We have had them here in Australia for years now. THey're only 206kW. or around 275hp. The last thing is driveline loss. THe WRX is All Wheel Drive and the Preld is only front. Much more power is sacrificed through driving 4 wheels than 2.
