yep almost all trannies will bolt right up, as long as its the same series engine, si is the best as fouthgenhatch was saying closer gear ratios, if u use anything other than an hf or std tranny ur also gonna need the hubs from any non hf or std because the spline count and outer diamter of the axle shafts are different, but is suggest picking up the whole assembly from a junkyard car for 3-400 bucks and installing the whole assembly, tranny, axles, hubs and nuckles, and yes this can be tackles as long as u and ur friend have a decent amount of mechanical knowledge and the tools necessary to lift the car and get the get the axles out. good luck whatever u choose
