If you already bought the Is250, it would seem you have already decided. If your looking for more power out of your is250 awd there is not alot of aftermarket for this car yet, however you could do a few different things if your into spending lots of money. First find a wrecked IS f buy the engine and transmission, make sure to get the ECU and perhaps even the motor mounts. This is an engine swap and a pretty complex process that would absolutely void your warranty. Second buy a generic turbo kit, have a shop weld it up for you and send your ECU out to be reflashed. Third take a massive loss and trade your brand new IS 250 in on an IS f.
put some basic upgrades on the 250. take it for what it is and like it. if you want to go fast go buy a motorcycle maybe. the isf is only good during the summer jsut like a bike. or you could sell the 250 and get the isf and a winter beater
