to me i would go with the jdm itr conversion. most of these are becoming very common, but the one i rarely ever see or hear is the ae86 conversion. it is very sexy but im not sure if it is easy to find info on all of it. if you like old school go with that, but if you want more modern, go with the itr conversion, yes it is very expensive but if you look around hard enough, you will find a decent one for a good price.
