I don’t know much about these ls engines. My brother has an 06 Silverado with the 5.3 and he has his heart on turbocharging it. What all do you need to do to make a decent build that will start first thing in the morning. He doesn’t want something that he’ll have to work on after the swap and he wants to get around 20mpg.

Thanks

 

Go to ls1tech. tons of info on there. As much as I hate to say it sloppy mechanics on FB has good info, but you have to sort through the 90% BS.
