Need more fuel!!!!!

having the ecu remapped would be much better, if danny will do it you, then i'd av that done, otherwise, for a quick job do the 5th injector, i'd get an ajustable pressure swith, demon tweeks should have one, i'd get it on a dyno and see where it goes lean, then have the injector come in just before that.

many moons ago HKS has PFC F-con and GCC programmed for S12 silvia and aftermarket ECU. if you're lucky you might be able to find them.

I managed to get a HKS ignition module for my s12, but it was six years ago. Plus all the instructions were in Japanese and I had to get them translated .
Don`t think they are still available now though.
