I'm doing the same thing to my car right now. I have a 94 civic hatchback dx automatic and i'm putting in a 95 gsr motor. I'm not sure if you can use the clutch cylinder and other parts from the gsr. I bought all the parts from a civic instead. Today is day two of the project and the biggest part is cutting and welding on the manual tranny bracket because the manual bracket sticks at a 90 degree angle instead of a 45 degree angle. Bakeoff, a member on this board, has done a couple of these auto to manual swap and he didn't even cut and weld, he just bolted on a metal plate to adjust the shift linkage, but he never got pics for me so i didn't know what he did. Other than that, it doesn't seem that hard if you have all the proper parts. I will tell you how it goes and what you need to look for.
