i wanna get fuel injectors for my 94 z28 but i dont know which ones,stock or upgraded, can anyone help?

 

No sense in going with upgraded injectors if you don't have the mods to require them. A sig with the year, model, and mods to your car would be helpful. If you are looking for just a stock replacement set for an otherwise stock engine, I would stick with a stock GM replacement or you can go with an aftermarket brand such as the Ford SVOs that make them in 24# sizing, which is the stock sizing for the LT1. But once again, more info. would be helpful.

 

You want to or need to?
If you just need some because some broke, then get stock replacements. There are usually some in the for sale section.
If you want some because you think you can get more power, do a search first.
