What are the things you can change before the actual swap?

GA16DE in 96 Sentra GXE is the car the DET is going into.

I know there can't be much to change because most of it comes with the swap itself. But can you go ahead and change fuel lines and fuel pump? What preparations can you make for a DET Swap?

What about sensors? What about accessories and placement in the engine bay?

General question is... what changes/preps can be made to the car before the SR20DET is ready for the install?

you could change the fuel pump but there really isn't anything that needs to be swapped that can be done with the GA16 still in it and your gonna get blasted for not searching.

No need to change the fuel lines. Do some searching, its not hard.
