Look at Jay Racing
, they have created a timing belt tool kit for the dsm and evo 4g63's so check them out. An evo has evolved but its still a dsm in my mind so remember, over build and keep up with preventitive maintainence (belts, plugs, fluids) do them early and often. Oh, I have heard of people doing this without the tools but if there is a way they are keeping it to themselves. Good luck.
