Hi all, I am new to the turbo scene and am considering a big boy combo. I know my way around an NA build, but am thinking of a turbo build to push 4600lbs into the 8's and drive daily. It's a TBSS, w/ 4l80e, full weight. My biggest questions are what breaks constantly? Maintenance schedule? How big do I need to go turbo wise to get me there? 88-106mm single? Thanks to all, sorry for the newbie questions. I have worked on some basic eBay turbo builds on old blow through stuff, but the bigger power stuff is new to me. Thanks for any info.
