Power should be the same. The older 102 and the newer 102 use the same pistons, rods, and heads. The only difference in the motors is weight, looks, and a different reed valve block. The newer reed valve block may give it just a tad bit more power. I need more weight up front so the older style works good for me. Though I do have the newer version also. If you get an Evo. model, just make sure you have stainless bolts in the heads. Not the aluminum ones some models were shipped with.
