There will be no turbo included with the base installation kit but can be purchased through us HERE I really like the billet S480's on these trucks, even with stock injectors and a sportsman CP3.

***COMMONLY ASKED QUESTIONS***
Q: What colors do you currently have in stock?
A: The colors listed in the 'Powder Coat Color' drop down menu that you are able to select is what we have on hand, ready to ship. This is always updated and real time inventory with what we currently have. The colors that are unselectable are what we have in production and could take anywhere from 6-8 weeks for us to have available again.
Q: Can I order this kit raw?
A: Under no circumstances are we able to ship a raw kit that is not powder coated.
Q: I am looking to piece together an S400 Compound kit and don't need everything you are offering in this listing. Do you sell the individual components?
A: We sell the following items by themselves but these are typically used as replacements. Coolant tank, pedestal mount, down pipe and battery tray.
Q: I already have an aftermarket y bridge kit on my truck, can you exclude that from this kit and give me a discount because I dont need it?
A: We cannot exclude any components from these kits, even if you have them already. This is a complete kit that is already assembled and cannot be separated. We suggest selling the current kit on your truck and putting the money towards this and starting fresh with the components included here.
Q: I'm thinking about doing the installation myself, how hard is it to do?
A: The installation of this kit is not entirely difficult but it is a long process. We figure around 20-30 hours of labor on average to install this kit. You will need to drill and tap the upper oil pan for the atmosphere Borg Warner turbocharger to drain back into the engine. This requires a 3/8 NPT tap and 37/64 drill bit. We often use the location right next to the starter. We highly suggest going with the -10 return line kit in the suggested items above.
With this compound kit, you also have to relocate the passeneger side battery which will be moved to behind the passenger side headlight. In some cases, you will have to extend some of the battery cables. Those two items are the most difficult part of the whole job.
Q: How long does shipping take?
A: We ship most orders same business day as we receive them (Monday through Friday). This also depends what time during the day we receive the order. If it does not ship the same day, you will see tracking the following business day. All kits are located here in Pennsylvania so figure 1-3 days for east coast to mid west. 3-5 days for central to west coast.
