I'm running 3rd gen housings in my S4 but I just now realized that it only uses two oil injectors. I want to keep the metering pump, Can I just put two solid bolts in the two extra holes that I will have on the pump?

 

yes you can but the amount of oil injected total will be insufficient. you will have to premix as a supplement if you do since the FD OMP won't work on the S4.

 

The 13brew rotor housings have 2 oil injectors (1 per rotor housing), just like your s4 ones. There is 2 oil injectors in the S4 lower intake manifold. Use your S4 lower intake manifold and you will have a total of 4, no different than before. Tada!

 

for some reason i was thinking of the REW irons, which wouldn't accept the n/a LIM.

 

So the REW engine only uses two oil injectors, as opposed to 4 injectors on the s4/s5?

 

The 13brew has an oil injector in each rotor housing. However, the 13brew no longer has the 2 addition oil injectors in the lower intake manifold like previous series.
