Hehe..
I'll be nice, differences in the actual engine, I'm pretty sure there aren't any major differences. The extra few ponies that the J-spec puts out are from a less restrictive exhaust IIRC. The Jspec however has less emissions related material, the UIM for instance is different on the TII. I'm kinda tired otherwise I would go father in depth.
