This is a walk-through for anyone who is attempting to wire a standard RB25DET Neo into an R32 4-Door Non-Turbo Skyline.
The car that I have done the conversion on is a Skyline GTE - (Manual RB20E). This walk-through will work to a tee with this car but I cannot guarantee it will work with any others. Although I would not be surprised if it worked on other cars with an RB20E or RB20DE - if someone could confirm this it would be good.
It is also assumed you have already removed the previous engine and wiring loom and have installed the complete engine, standard loom, and sensors from the RB25DET Neo.
This is primarily a wiring guide as there are plenty of other tutorials floating around for engine and accessories installation. It will be broken into several different stages as I am still working on a couple of things.
Also, if there are questions you have regarding anything else please don't hesitate to ask because I am going from memory on this one.
