Is there a list of injector codes out there that I can look at to tell what each type is for?
And what would occur if I put turbo injectors in an NA engine?
Here is sort of a list, doesnt really specify the difference between the models though, just what year each code injector came in. I'll just copy and paste it from Oregon fuel injections website.
A or AA code injectors: 6.9L 1983 and early 1984 models
B, BB, C, or D code injectors: 6.9/7.3L 1984-1992.5
E code injectors: 7.3L 1992.5-1994
G code injectors: 7.3L turbo diesel 1993-1994
Okay, here is what I have gathered. Yes I fubared my injectors, there leaking, lets not get into that, it always seems like people start posting off how did I do that and what not, lets just stay away from that
. Anyways, G code injectors, that came in the turbo motors, have a different shaped tip, which is hardly noticable by a quick glance, and you would only notice it if you were looking. Its more of a U shaped, rather than a V shaped (on BB codes anyways). I guess they have slightly larger holes in the tip, nothing much bigger though, some crazy small number like .002" if I remember right. They have a higher pop of pressure, so this is where it gets kinda tricky. If you stuck in new G codes injectors, and had the timing set for BB code injectors, your truck will run a couple degree's retarted. This is because the higher pop off pressure means it will take a fraction of a second longer before the pressure in the lines is met and the injector will fire off. So, you would have to compensate that by advancing your pump slightly. With the turbo pump, I believe they are calibrated for the difference, and they in turn run a little more advanced than a regular N/A pump. You DONT need turbo injectors when you turbo a N/A IDI, they are not required. Some say you can get more performance from G codes, others say they are more of an emmisions injector. Its all up to you, but when I go to buy new injectors, its just going to be BB codes.
