So I'm fairly new to the world of Nissan and I was just wondering what the main differences are between the KA24E and the KA24DE in specifics? I understand that the DE has little more horsepower and a few slight differences but I am trying to figure out what exactly they are. If anyone has any insight feel free to post me an answer. Thanks!

The KA24DE is a Dual overhead cam design. That means there is a separate camshaft that actuates the intake valves and the exhaust valves. The motor has 2 intake and 2 exhaust valves per cylinder. The KA24E is a single overhead cam design. It has 2 intake valves and 1 exhaust valve per cylinder. The DOHC is better in every situation unless you are trying to build a high horsepower naturally aspirated KA, but not many people do that because it costs way too much money for the power you get out of it.

I believe the SOHC has higher compression pistons. In terms of swapping, the power steering pump is on the opposite side of the DOHC, and I believe that the SOHC PS pump mounts to the head instead of the block. I may be mistaken on this though

There is a specific thread we have for newbie questions, so you may want to try there instead of starting a new thread for a little while. If you post there, no one will flame you no matter what your question is.

mainly the ka24e is a single cam and the ka24de is dual cam. other than that it's just little differences like different locations for things.
