Complete twin turbo kit: This turbo kit PROUDLY made in America is designed to bolt up directly to your factory exhaust manifolds and retain all factory OEM accessories with minimal to no modifications. With upgraded turbos, accessories, and adding a proper boost controller setup we have made in excess of 1400hp with the use of this setup on a stock cubic inch engine. Larger displacement engines with larger turbos will be able to make much higher power levels if desired. 
All initial kits will be fabricated and then tested for proper fitment on one of our shop cars prior to being shipped. If you are thinking about running turbos other than what comes with our complete kit, please contact us prior to purchasing so that we can help you make a decision, and so that we have your turbos in stock when it comes time to test fitment.
Kit Includes: practically everything required to have a functional twin turbo setup installed. Depending on your power goals and the fuel type you will be using you may also need to upgrade your fuel system and injectors. This kit also does not come with a tune/tuner, and you will be required to have it tuned by your tuner of choice. We would be happy to help you with this as well and you can click here to see our available remote tuning options.
2 turbochargers: We spec'd these turbos for their ability to spool very quickly on a stock application as well as be able to deliver over 1,000whp with supporting modifications. I.e. adequate fueling.(Not American at this time and subject to change in the near future) Several band name upgrades available in options

          Intercooler: Front mount 4.5" thick core air to air intercooler that will support upwards of 1,000hp, We also have more efficient upgraded options such as out 6" intercooler as well as intercoolers made with Bell cores
          Charge Piping: We used 6061 aluminum cold side piping to help dissipate heat and save weight, the latter being a great feature due to CTS-V2 already weighing in at over 2 tons! All pipe ends that will require a coupler mounted to them will have a bead roll for strength as well as to help keep the coupler on under high boost pressures.
          Hot-Side Piping: We used T304 stainless steel piping for the hot-side and down pipes to help last the lifetime of your vehicle. Our hot-side piping was designed to mount to your factory exhaust manifolds for a quick easy install without need to modify you vehicle and its accessories. This system has been tested to fit full frame t4 turbos ranging up to 76mm and possibly larger, but we can custom fit most any turbocharger you wish for an additional fee. We also designed our hot-side piping for maximum boost control efficiency by spending the extra time to optimize the placement & location of the 44mm wastegates.
          Downpipes: 3" Stainless Steel piping made to come out of the turbo and run into the tunnel and comes with 3" V-Band connections to be able to have your local exhaust shop easily connect to your factory exhaust. Downpipe will come with four o2 sensor ports. Two for upstream o2's, and two plugged that can be used for a wideband if needed. 
          O2 extension harnesses. 
          Oil System: Our kit comes with everything needed to feed and return oil to and from your turbos and requires no drilling and tapping as it comes with a Turbo-Werx Exa-pump to pump all oil from the turbos back up into the engine.
          Intake Manifold: This complete kit comes with an OEM LS3 intake manifold and fuel rail. This will make it so that you can re-use your factory LSA throttle body, as well as have an easy to install direct plug and play factory fuel rail setup without the need to replace factory fuel lines.
          Misc. Accessories: High quality fittings, hoses, and lines required to feed oil and vacuum where needed. 
          Installation Hardware: High quality reinforced silicone couplers with high quality stainless steel T-Bolt and VBand clamps where needed. All grade 8 or better mounting hardware. 
          Easy to install with little to no physical modifications to your vehicle and no special tools required.
          Installation instructions included with advice and tips to help you through the install.


          Basic turbo kit: Only offered to Dealers & Shops, and will come as a basic kit with complete Hot and Cold side only, without turbos, intake manifold, wastegates, BOV, and all other accessories. This kit would be something perfect for a performance shop to sell to their clients as they would generally already have the ability to supply their own parts, fittings, hoses, etc. (Dealers and shop owners please contact us as we will work as hard as possible to get this price lower for you)


          Oil-less turbo upgrade: This option will remove the complete oiling system from our kit and will include everything necessary to run Comp Turbo - Oil-less turbochargers, including a grease gun, and 2 3oz tubes of Comp Turbo Grease This upgrade is recommended (but not necessary) for anyone who plans on driving their vehicle often or daily. The reason we say this is due to the ease of maintenance, as well as removing all oil lines from below the vehicle. This helps prevent potential road hazards and other debris from possibly hitting the oil lines causing damage or worse ripping them off completely, which could lead to catastrophic engine failure if not caught quick enough.  
          Custom Fit Your Turbo of Choice: We can custom fit your turbos of choice to our turbo kit to allow the use of different turbine housing inlets and sizes I.e. T3 T6 or V-Band.
