Officially kicking off this Saturday, August 25th is a new Forza Motorsport 2 tournament challenge where the grand prize racing winner will be rewarded with a brand new Nissan Sentra SE-R Spec V. To participate, you'll have to complete a few steps first registering by either heading to the XBLM to download the free tournament theme or signing up online. Once registered, you'll need to download the free Forza 2 Nissan car pack and race in the qualifying rounds (which start this Saturday) through September 8th. From there they'll be wittling down the racing participants and crown the Nissan Sentra SE-R Forza Motorsport 2 Online Tournament winner at the LA Auto Show in November. If interested, check out the complete tournament details, rules, prizes and more after the jump.
