I'd say having $10-15k tucked away is a likely safer bet. You need supporting mods and account for any other misc. stuff along the way. If you have the base, w/o the sports package. You should probably upgrade a few things before going FI as everyone has stated. LSD, brakes, clutch, suspension, that sort of thing. As far as being worth it, I'm pretty sure that extra bump in hp is gonna put a smile on your face.
