Default Ls1 injectors

Im building a mild 355 and i plan to run my fuel psi at 60 like ls cars.
i was given a set for free and i know that my stock 93 injectors wil not be enought im just looking to see if any one has done it or if i should just find some 94-97 injectors and run the 60psi

I have a set installed in my bolt-on car.......They do work nicely but they are what they are weather you have the 26 or the 28.5,why crank fuel pressure up that high just to use Ls1 inj....you are better off getting a set of SVO30lb inj or some racetronix 32.2

Your stock 93's would be 26# at 60 psi or you can run the LS1 injector at that psi and have either 26 or 28 depending on what you got.

Don't run any more pressure than you need.. the injectors start to become less balanced as a set the more pressure you run. The SVOs at 3 bar should be fine with your setup. If not then you can turn up the pressure

At one point I was running 32lbs LS injectors at 58psi, now running 36lbs Trickflow injectors with a stock regulator.

IMO get lbs per hour with injector size NOT regulator. Many of the adjustable LT1 regulators have reliability issues, stock regulator works great.

Basically you can do this but in changing the regulator you are making a compromise to reliability, might never fail, but much more likely to than the stock regulator.

Just get the SVOs and run them at normal pressure, they will be more than enough for you. Or get greentops if you are worried they won't be
