So I came across a good deal on a universal STS sytem that I'm putting on my 8.1 4x4 Silverado. I'm running on a limited budget so the cheaper the better. What are some good plugs to run on this setup? I don't quite know how much boost this moter can handle stock either. 5...7...9lbs?? What is a good, but enexpensive(as possible) upgrade for the fuel delivery system?

I've got other ?'s but cant think right now. Any help would be great.

 

did you get 42 lbs injectors with the kit i am running the sts setup to...

 

Welcome to the site! as the questions come pour them on us, and dont forget the search button, its your new best friend.

 

No, it didn't come with injectors. What should I use on the big block? I've hears 80#.

 

well if your running just the basic setup i think that the 42 will work...im tryin to find some 60 lbs here are my mods...6.0, port polished 317 heads, custom turbo cam, water/meth, msd wires, intercooler, 410 in ther rear, trying to achieve 500 rwhp

 

Im looking for 60# to go with the whipple. Havent gotten to far.

 

What about boost, what can this motor handle. I want some power but I sure don't want to blow it all to hell. It is a daily driver!

 

I would start at 5psi and work your way up with supporting mods.

 

What all are "the supporting Modifications"

 

Stock pump should be fine. I would go with at least 60# injectors. None intercooled 5 psi max. Intercooled 8 psi would be good for reliability.
I run NGK TR6 plugs.
BTW you WILL have to run 2 38 mm wastegates! I'm having problems with boost creep on my truck and I'm running a 42 mm racegate. AKA I can set the wastegate at 4 psi and it will go to 12 psi.
