I am planning on doing a diesel swap in my 94 toyota pickup 4x4. I currently have the 3.slow in it with the A340H tranny. I am thinking about the OM617 swap. I am new to diesels so I'm not sure what diesel would be the best for this truck. Any suggestions would be a big help and a list of things that I would need to do to get this done. As I said any suggestions or help with the OM617 swap would be awesome..

Thanks
