5 spd swap will require you to add the clutch reservoir and clutch pedals bypass the neutral safety switch and wire in the reverse sensor, the d16y7 is non vtec so you will be losing power but so long as you have the obd2 ecms from both cars they are almost plug and play with each other the difference being that the d16y7 does not have the vtec. The vtec ecm will not run the d16y7 properly it will have incorrect fuel curves and other issues. What you can do is put the d16y8 head on the d16y7 block and the rest then is plug and play for wiring as you can use the d16y8 ecm. However keep in mind that many who have done this have had issues with the bottom ends giving out as the bottom end is not as strong as the d16y8 bottom end. If you are not bagging on the motor every chance you get then you should be fine using the d16y7 bottom end, and it will give you a slight hp increase to about 135 hp over the 130 you currently have with that engine.

it can be done over a weekend, if I remember correctly there should not be any new wiring as you are going in the reverse that most ppl do its just that you will not be plugging in the vtec controller. You will need to swap computers though as the vtec ecm will not run the y7 properly.
