if you know people you can build a nitrous kit for about $150-$200. i have a few friends that have built a wet nozzle kit for about $200. the shift kit i did the j-mod to mine and i have about $30-$40 in my set up. i found the directions on the TCCOA web site then all you have to buy is gaskets, fliter, a few drill bits, and of corse trans fluid. it would be a good idea to upgrade the 1-2 shift piston also do it now before it breaks so it does not scar the bore up and trash your trans.
