injector size one of my injectors in cylinder 5 gets stuck open every now and then and im tired of having to deal with it. so im thinking of just replacing all off them to better ones since im going to be in their. my question is what size are the stock injectors and what size do you guys think i should get? i have absolute no idea if i should even get bigger ones of just get the same size?
The stock injector is 28.8 lbs/hr @ 58 psi. If your planning to replace your injectors, the cheapest route is pick up a set of used stock injectors from an 01-02 F-body or 01-04 Vette. If you are planning additional mods down the road, I would invest in a set of larger injectors that will meet whatever your hp goals are.
I think the Ford 30 lb/hr injectors are rated at 43 psi. They will flow 34.8 lbs/hr @ your stock fuel pressure (58 psi). You will definately need a tune to run anything other than the stock injectors.
