Sportsguy83- ill look at that in just a minute for you
brocktwalker- the 4500 base kit uses the non Tial SS housing version of the same turbo yes, the 6200 premium kit is what uses the same Tial SS housing. but you are comparing a turbo kit with a base map to a full installed turbo system with all of the added items I listed above) can we do the system for less with out all of those components, yes, but we were among the first shops to turbocharge these cars and that is the system that we put together to do it... since then many other options have become available, which is why we sell those as well.
