You keep saying strong and V-6 in the same breath. You don't need strong in your car. You need cheap to go along with college student. Get the cheapest one if you feel you MUST upgrade your 7.5. Have you broken the 7.5 yet? If not, then it is all you need. Back in my catamaran racing days we had a saying...If it breaks too often, it's too weak. If it never breaks, it is too heavy. "Expensive" should come in there somewhere but we always seemed to ignore that part of it.
