So there are two full pages of posts on this thread about upgrading the transmission, but no one has said anything about an LSD. This is one of the most important parts of a well built transmission. With even a basic viscous one way differential you would be able to put down all of your horsepower more efficiently than with a standard open set-up. Spend the extra money to get a good one and you will have traction beyond your wildest dreams.
