THATS A NEGATIVE GHOST RIDER.
The series 4 ecu will not control the series 5 OMP, so he will either need to switch to all s5 stuff or swap the omp for a series 4.
seeing as you already have the s5 injectors, why not just find a series 5 afm and pressure sensor and ecu. try ebay or rx7club. always na parts floating around from people going to turbo swap. just make sure to get series 5.
