B18c1

I have a 2000 Honda Civic Ex. I decided to make an exchange at a B18c1 but I'm not sure what all is different between this engine and my engine stock. I was wondering what all I need to change or buy in order to have an exchange of success in my Civic. Thank you in advance!

i wouldnt waste the money-now, when the engine is worn out, I could be cheaper to buy with the Honda engine in it already
