I have recently changed out my kit to the r1000s . The kit is a complete kit . The super B turbo was on truck first and has about 1000 miles on it. I then upgraded it to the twins and if that has 500 miles on it thats alot. They were too small for the p pump. I will include manifold as well, it needs to have 2 studs drilled out . It is an ats manifold new is $480. We would have to figure out shipping as these boxes are heavy. Asking $2500. 00 Any questions please feel free to ask.
