Frankenstein engine??

Frankenstein engine??
I'm beginning to get really confused/frustrated with this engine. When I removed the UIM, I found that the previous owner found it necessary to splice a third plug for one of the primary injectors. I removed the injectors and found out that I have three high impedance and one low impedance.. on my s4. I decided to do the omp removal/ premix mod and when I went to plug the holes, I found that the bolts (10-1.0) didn't fit. It turns out the 10mm-1.25 fit perfectly and now I'm really confused because I was under the impression these bolts were the thread pattern for the turbo engines. Anyone have any ideas?

The car is an 87. The plugs are different for the low and high. I have three offset plugs and one centered. There is no doubt that there are three high and one low. What I'm wondering is if there are any N/a engines that have the 10mm-1.25 oil injectors? If not then I must have a turbo block and most likely turbo rotors too.

I'm fairly sure that all oil injectors are M10 with a fine thread (1.25 I guess according to your post). I can't ever remember seeing one with a different thread and I have swapped the injectors across all 2nd gen 13Bs (and GSL-SE 13Bs) without issues.
Weird about your injectors though.

That would make sense that the other owner fooled with the injectors. I thought the thread was 1.00 because of the premix writeup here: https://www.rx7club.com/showthread.p...ht=omp+removal
It says double check but I figured someone would have said something if it was wrong by now.

Measure the impedance of your injectors with a Ohm meter.
also post the ECU number(like N326 forexample) and see if there is a resistor paclk on the car,near the AFM and shock tower/passenger side front.
