I have a '93 D15B7 that needs to be replaced. I have searched thread after thread, but am still unsure of my options. I understand that staying with a D series is the easiest way to go. I want upgrade slightly to gain some more power, but not to race, as it will be used only as a daily driver. I need to find a thread or advice that tells me what will need to be changed to ensure I can connect everything and drive when done.

For example, can I install a motor from a 97 Honda Accord?

or somthing like this

I will need to perform this swap as soon as opssible because I don't have a vehicle to drive now. Any advice is greatly appreciated.
