stock injectors? 87 GTA

I found that 1 of my injectors are dead and 1 is intermittent last night, I want to replace them all but have no idea what size they are. I do not want oem again because the injectors are known for having shorts and just problematic.

What size are the stockers? What would be a good brand / size to swap them too? I am looking to pass smog too..

My motor is stock.


Thanks all

Re: stock injectors? 87 GTA

GTA has the 5.7 TPI. I have heard people like the Ford 24lbs injectors as replacements, is this a good thing for a stocker?

Ok, thanks for all the info.. I am not gonna mod the ecm anytime soon, so I will just get a new bosch set. I thought the 24lbs were a bit much with no mods.

Thanks!
