04 5.3 Sierra power build
#1
Hey everyone I'm new to the site. Have been considering my options as far as power adders in my truck. I've done the obvious intake exhaust and tune. I am seeking a turbo kit to make some good power to the wheels. Wondering what everyone else has and what they're getting for reliability. I am looking at the on3 single 70mm kit. My ideas are for now get the kit studs and gaskets and see how it performs. Just wondering what I should have to worry about. I have heard the engine can handle light boost with stock internals. Just want to hear from others that have done this already . My goal is a 500-600 horsepower build in the long run
