Hey, my name is john I have a 2000 Silverado with the 5.3. I'm wanting to go turbo on a budget build. My engine is all stock besides tbss intake swap and cai and long tubes on it now. I have been reading a lot on here bout turbos and set up. my engine has a few miles on it too. I wanna run somewhere between 8-10 lbs. I know i will need to run twin 250's or a single 340 fuel pump with 60 lb injectors. what is a good turbo to use? I have some friends that have ran the on3 70mm. and also have read on here to where some people run them being that you can get them for $350. whats yalls input on them? im probably goin to build a 5.3 or do a 6.0 swap later on down the road.
