Alright so with this whole fuel injection stuff that I'm doing a few things had to go away.

OMP, Hose and Injectors: Can anyone provide a picture of how its done with the oil injectors? Does the 12a pump still get used or swap for a 13b one?

Coils, and igniters: Do you guys just power them up from the same location of where the stock coils are setup?

Let me know, and pictures always do wonders.

what exactly are you doing? swapping from a 12a to a FC 13B?

S5 are electrical OMP and S4 is mechanical.

No i'm fuel injecting my 12a. So for the OMP, I don't have a carb to feed it in. So will the 12a pump work fine with it?

I would imagine that the 12a omp is calibrated to be used with the nikki's fuel curve. Just to be on the safe side I'd use the gslse's omp or the 86-88 omp.

I'm curious to know if the S4 fuel injection intake manifolds will fit to the 12a or what manifolds are you using?

I know the header will not fit, there is a 10mm difference in size between 12a and 13b. I would imagine the IM being the same way?

^Correct. You *could* make an adapter plate, but dj55b is going a different way!

As kgray already knows lol ... I bought a Racing beat Side Draft manifold, and will be drilling and tapping holes for the Oil Injectors. FI/Carburated, the amount of oil needed to get inside the engine will always be the same output. I just don't want to go through the hassle of premixing.

How are you going to have the OMP linkage hooked up? It might be best to go with a S5 electrical OMP if your megasquirt is capable of controlling it.

That's a very good point ther Kgray that I haven't even though of yet. Anyone know if the s5 will actually bolt up to a 12a though?

kgray

Steve? BREW swap guys? haha

If I'm not mistaken, the S4 13B metering oil pump will bolt to the 12A front cover. The mounting flange looks exactly the same.

Best bet for running the injectors is to drill and tap your new manifold. You won't have the benefit of the rotor-housing mounted injectors in the later 13Bs but I suspect you'll do fine.

To control the pump, use bicycle brake cable and make two mounting brackets to hold it in place.

Run new wires from you master fuse panel, with a relay to switch them on when the key is set to IGN.

Aaron loves adapting bycicle parts to cars. Thats a great Idea and will try to do so.

Also I will do that for the igniters and coils. I'm going to be putting one of these fuse boxes inside the engine bay intead of the stock one. It will most likely be mounted beside the hood release latch or something.:
