I've tried searching google among other places and I such at forum navigation so if someone can point me to the right place I'll be happy to read up ur my question is I want to buy a motor to build for my 06 xt but I'm lost as to which I can use and can't. Are all ej blocks the same over the years other than being closed/opened deck and internals or do I need a specific turbo block to rebuild...thnx in advance appreciate all the info I can get.
