Honda civic engine swap d16y7 to a d16z6?

Alright i got into a accident few days ago in my Honda civic ex that has a d16z6 VTEC engine got totaled like body wise that requires money to fix the chassis our of place the frame etc. Luckily the engine is still working and i put a new transmission in there 2 months ago with 1yr warranty. I bought a honda civic 1996 DX with a d16y7 engine. Now the car is okay but the d16y7 is like really slow and the transmission is bad . i want to swap my d16z6 into the 1996 dx but i don't have a clue as to what i can keep etc pumps/radiators . Do i just grab the engine block and the transmission and drop it into the Honda civic dx 1996 and just buy the wire harness everyone keeps telling me that i will need? some 411 on this would really help i'm a complete freshie when it comes to cars, although my dad would be doing the work he's never done it on a Honda he's always done engine swaps on his American muscle cars so i just want some insight and advice or a how to . Thank you in advance.
