Ive got an H&S single turbo kit(without turbo) for sale looking for $1100. Includes everything but up pipe gaskets and bolts. Going a different direction with my truck and only ran the kit for a few thousand miles. Kit installs easy even cab on.
The kit worked really good around town, highway(did a 1200 mile road trip the morning after install) and just daily driving but i didnt like how it did with towing a bit heavier(10,000+). Thing straight ripped as a toy but i cant keep the truck as just a toy.
Yeah ive heard great results from that. I would play around with turbos some more but just gonna toss my stockers back on for the winter until i decide if ill upgrade the atmo.
