Because it was designed off the LS1/6 intakes, the 102 is based off the LS2, hence the use of LS2 injectors. LS2s are shorter and enter the intake at a different angle. Thats why there is a spacer needed for LS1 injectors

Now what kind of injectors should I get? Im not too familiar with the differences of flow matched, low impedance etc

I am looking at these, minimum for my setup calculated at 46# injectors, I would like to have enough injector and not have to worry about duty cycles.

Somewhere in the area of 48-52lbs/hr would be a good minimum. Those 50s would be good. You could even get away with the 57lbs/hr, those would give you some room to grow as well

So is an injector an injector? I will either get the 60lb Siemens or the 57lb FAST's in that case.
