I bought the civic one because it lines up with the existing hole and has an extra row so maybe 30-40% more cooling and a larger heat capacity so will soak up bigger short spikes.

Haven't gotten as far as putting it in yet. I did get an OEM fan for it for $20-30 off ebay which will fit once the fan and so on is gone from the water pump but I'm going to an electric pump. I've also got an a15 so the thing will probably be a bi overkill but I have dreams of turbo so I wanted it big enough for when I finally get that project going....

Other things to consider is the inlet and outlets are 32mm and where they line up with the thermostat. The inlet lines up with the cyclinder head (more or less).
