(I'm pretty sure nisson93 has a '95)^If you have your s14 harness you dont need his, or the mani technically. just the s14 dizzy(Which you should still have one from your old motor), yes you could convert to s14/s13 harness and run an aftermarket coil(MSD,Jacobs,etc.) but its a PITA and S14 dizzy/internal coil is strong as Fuuu, not really neccessary.

Also use your s14 a/c bracket and compressor(IF your using a/c)
