The truck in my sig injector duty cycle is 100% at approx 80-90% TPS. I need upgraded injectors but I was thinking used injectors cost $250, I might as well upgrade everything and do a nnbs intake with stock injectors for close to the same price but a little more work. I found an 07 e85 Tahoe intake manifold with stock fuel rails and stock injectors (injector part #12594512). Im looking for some experience or oppinions. What makes more sense for the long run. Upgrade my stock injectors to 8.1 marine multech injectors. Or upgrade to 07 intake manifold. And if i upgrade to 07 intake setup will the stock injectors be enough for my engine. Any oppinions or advice would be helpful. I know the nnbs intake manifold is returnless and takes some work to make it function correctly.

 

Yeah but you have to do customizing to your going to fuel/return style to returnless style...you have to get a Corvette fuel fliter so you can run it..I think, maybe some of the boys can give better details on it

 

What connectors are the injectors for the 07 intake manifold. I believe i have delphi's. Will the e85 injectors work with my fuel system or will i have to switch them out for something else.
