OBS injectors in a SD?

[taterthedog]

Are OBS injectors smaller than SD ones? I'm going to swap some parts off an OBS into my SD to try to narrow down an issue. Can I use the injectors? Will it require different tuning? What if I just tried one?

You cant swap the injectors without tuning, the OBS injectors are single shot and your SD is split. They are also a lot smaller.

Obs are single shot, sd are split shot. I'm pretty sure it can be done with tuning but not without
Edit: treed

OBS injectors are AA or AO injectors which are about 90cc per 1000.

SD injectors are AB or AD injectors which are 120 per 1000 or 140 per 1000...

OBS injectors are single shot, SD are split shot.

There are some 96 and 97 OBS trucks have AB injectors but they are not typical.

Do not install one or two AA or AO injectors with the rest being AB's or AD's.

Thanks, that is what I thought. I guess I could use them for cores.
