I was wondering if anybody could tell me, or show me a link to, the differences between a b16a1 and b16a2 longblock.

My plan was to purchase a longblock and start building it, but seeing the difference in price(at hmotorsonline, 900 for b16a2 and 499 for b16a1), I thought that if their isn't much difference I could get the b16a1 and build it then get all the necessary parts for my car. Remember, I'm just getting the longblock, then doing the internals, then I plan on changing it so it can have and obd 2 ecu, if that is possible


My car is a 1996 civic dx coupe.

Any info would be greatly appriciated
