Car will go faster than most people (or the law) can handle. I really don't know how long the engine will last. Mine was running fine at 350k when the little girl totaled it. Probably somewhere south of 200k you'll want to replace all the rubber hoses and such in hte intake system, including the 8 fat ones betweenthe two intake manifold sections. Replace the injectors at the same time. Not cheap, but will make a big difference. You found a really good deal. Enjoy the car and ignore the fuel costs.
