A used kb can be found for under $4000 easily to those that think you will pay over 4-5 grand for one. I bought my 2.1 for 3200 after selling my procharger for 3000. There's a couple of 2.6 kb's on svtperformance right now for under 4000. Tt isn't a bad route either, I haven't owned them but I have installed them and besides the tt setup itself the rest needed can be found for cheap putting it together yourself. And as roush said those old roush/svo setups are sexy and easy to work with as well.
