Ok I hav questions to ask I hav a stock d16y7 wit the stock manifold an I was wonder if it's possible to swap out an go wit skunk2 manifold..an if so do need to swap throttle body wit it

 

You would need a y8 style throttle body & throttle cable.
You would also need a 5 speed 2 wire y8 idle air control valve.
You would need an ecu which uses a y8 2 wire idle air control valve such as an obd1 chipped ecu.
