B16a1 or B16a2 for my rex

[aznchco]

Im thinking about getting a b16 for my rex, either b16a1 or b16a2. I noticed that with the b16a1 ones they come with cable tranmission, while the b16a2 comes with a hydrolic tranny, whats the difference. also is there anyplace near reno, nevada that has a warehouse that carry these kind of engines, like maybe sacramento.
