imo, dont buy it for racing purposes..especially the ST version. there is no engine that can be put in that thing w/o doing tons of work. i mean opts are to turbo a 5sfe...but whats the point, it is stilla 5sfe and you will go through trannies quicker than oil changes. or to put in a 3sgte...omg what a pain in the ass that would be...put the factory 4ac in it and drive the helluv it.
