Can someone tell me what all needs to be done for the SOHC to DOHC swap... in a s13 90 and lower

I can get a Ka24de with 52,000miles on from a 95-96 240sx and i can get the wirning harness. The car is a AUTOmatic though So what wont work and what will...

the 95-96 car has these
The wirning harness is Automatic one
THe ecu is automatic one
Will those work...

Do I need power steering lines.... ?
Im going to be keeping my AC too do i need those lines too?

I know Ill need a new 5spd tranny or have to get the DOHC bell housing....

Someone just give me the layout of what all I need....!!

IM looking for a 91+ I have 1200$ to drop if somone know wheres there a good one close to INdiana...
If not then ILl have to buy a 90 or earlier and do this swap...

Is there anything else that will be diffrent on a 90 earlier that the 90+ have...

Thanks
