injectors?

Damn.

Damn what? You can only get the Pencil style if you switch plugs, and then when you do that your upping the flow rates so I wouldn't even advise using them if you cant tune for it. The ECM would have a major negative correction which is really bad.

Yes they have a better spray pattern and such, but that's what comes with the newer style and to use that you need to modify other things

Smallest Pencil ones are 22 or 21lb/hr IIRC... Since the only year they were around was post 99 and all 3100's and 3400's 2000 and up used the large bore intakes which needed the 22lb injectors.

22lb at 55psi...at the stock 43 they might not be all that far off.

Never thought about it that way. You may be right.

Did you try Witchhunters calculator to verify?

EDIT:
19.56 Lb/hr at 43. That's still a little too high for a stock 3100, but I've run my 3400 with stock ECM and 19lb injectors... I'm just not sure how much neg adjustment would be there with the small port motor.

Alright then the Delphi it is for me as well.

I do have the big port intakes(3400). But yes the wrong connecters.

Then the 19's would work in your case... aka 99 Chevy Venture injectors or similar. Same connector as you have now, just 19lb/hr I used to run those when I was OBDI.5

Yes! Thank you very much! I'm going to get them.
edit:
Looks like Rock Auto doesn't have the Delphi. But Auto Parts Warehouse does and at 86 bucks I'll go for it.
