JimmyHat and I did this exact same thing like 2 weeks ago.
You do have to change out the Exhaust mani and the distributer.
This swap is easy....Also there was something with a pipe we had to bypass but i dont think you will have to do it. Also i forgot to thank Taylor for some EGR assistance.
On the S13 there is a SHIT load of EGR shit....dont worry about it becuase the s14 has NONE of it. Just plug in what you can and forget about the rest.
