Huron Speed V4 T6 Turbo Piping for 99-13 GMC/Chevy 1500

*Fits 2wd, 4wd, AWD!

*NOTE: Currently this new V4 cold side has NOT been test-fit on a 99-02 front end. We expect it to work well with minimal is any tweaks needed. In the event it does not we still have our V3 99-02 cold-side we can supply!


New updates to the T6 kit:
*Updated crossover. This is a 2-piece design featuring a new design double-slip connection. This style of connection allows expanding and contracting without leaking allowing for some movement as well as a very easy installation and alignment to the manifolds. Not to mention improved ground clearance and no worries of a flex section failure.
*New manifold design with greatly improved wastegate flow. For the larger T6 turbos, they require a lot more wastegate flow to control the larger turbo, so we stepped up our game and greatly increased the wastegate tube size into a huge Turbosmart Power-gate 60 flange, the highest flowing 60mm gate currently on the market.
*New Downpipe, yes it recirculates! Our previous version of the T6 setup had a basic dump tube for the dp and the wastegate, not ideal for most. Now we have a full 4″ dp fitting through the frame and body with dual O2 bung locations. We also recirculate the huge 60mm wastegate with another double slip fit connection here for super easy install as well as leak free movement available! We include a 2nd piece connection tube to the main downpipe to get the exhaust under the car, and we include a version to fit both classic body styles as well as the newer 07.5-13 bodies. Lastly we also include a 4″ v-band flange so you can bolt to the end of our downpipe to add on additional exhaust if you desire without having to modify any tubing, just add on!
*Full cold side to make a complete T6 kit now available! See below info in cold-side section.
New updates to the cold-side:
*Much more simplified routing. Previous design would route under the frame to the intercooler and required different versions to fit classic and newer body styles. The new design wraps around the radiator and fits BOTH classic and newer body style trucks!
*All of your MAF or No MAF needs! We now include a very simple connection piece in so you can fit up any of your needs for MAF or Speed Density. We include the couplers needed if you wish to retain the older barrel style MAF. We include a section to use the newer card style MAF. Lastly we include a section with a threaded IAT sensor bung if you wish to go Speed Density, we have all of your bases covered!
*Cleaner look! Cold side tubing features a very nice and clean look in the engine bay, opposed to the old style that would quickly get lost. We understand functionality is most important, but to also look good doing it!
*Solution to the expansion tank! Previously the OEM coolant expansion tank would get in the way of cold side routing with the many designs available. We solved this by simply removing the OEM expansion tank (which is extremely ugly under the hood as well) and replacing with a very nice fabricated aluminum overflow tank. We now include a new radiator fill area that easily installs in the upper radiator hose to clean everything up and give a lot more room for a clean cold-side install!
*Fits all! Our cold-side was designed to work on both Classic body style trucks and Newer 07.5-13 body style truck. This means if you ever change trucks that happens to be the different body, everything will swap right over! Or if for some reason you need to let go of your turbo kit, your market to sell to will be greatly increased! Did I mention it also all bolts right up and fits the T6 hot-side? That’s right, the cold side now fits and includes everything needed to fit Both the T4 and the T6 hot-sides, as well as Classic and NNBS Body Styles!
*Accessories. Kits still include everything you need to set up the oil feed and return on the turbo, all of your gaskets for the turbo and new v-band copper O-ring gaskets, coolant hose extensions, Large 4″ intake tube with very large 4″ filter, Blanket for your turbo, and more heat protection such as a full roll of heat wrap for anything you may need!
Enhancements in all areas of the kit for improved fitment, function, ease of install, and compatibility.
If you ever change body styles, the kits now fit Classic and NNBS, everything needed for the changes in body styles in included!
If you ever want to switch from T4 to T6, changes are easy and the entire cold-side fits both!

Features & Benefits of the Huron Speed Truck V4 Intercooled turbo kit:

*Extra thick .120 wall stainless steel turbo manifold will have no issues holding up to the high heat and weight of the turbocharger. Worries about cracking manifolds is a thing of the past!

*Wastegate port is in the line of flow at the front of the manifold which will collect exhaust gasses from the entire system (both banks) as well as using a larger 60mm Turbosmart Power-gate flange to control boost. No need to worry about boost creep issues!

*Wastegate tube features a double-slip in line for an easy install and alignment of the wastegate recirc. with the downpipe for the recirculating WG discharge!

*No flex is used in the crossover pipe for worry of blowing. Added double slip to allow easy alignment, seal, and connection to the manifolds.

*Recirculating the WG Discharge into the downpipe is a STANDARD feature!

*Bungs for Primary O2 Sensors AND for a wideband O2 with plug is a STANDARD feature!

*System as a whole was made to provide a clean looking install, using great materials, built to make for an easy install without having to fight aligning pipes together along with easy to install v-band clamps. Boost control with a proper wastegate placement was high on the list to prevent boost creep.

*Cold Side and Intake Tubing made from Aluminum provide clean filtered air intake for the turbocharger as well as from the intercooler into the throttle body.

*Cold Side Tubing features a 50mm BOV flange and provisions to run any of the 3 MAF Setups (Barrel style for earlier year trucks, Card style for later year trucks, and No MAF w/ external IAT sensor bung for those running Speed Density.

*Included fabricated Coolant Overflow tank and Fill Tee removes the OEM expansion tank to allow for more room and a cleaner installation.


**Requires optional AC Line to retain the AC which you can add from the drop-down menu below. Everything OEM fits with just the need to change the hose from the compressor to the dryer.

**Intercooler and cold-side piping installation requires movement of Trans-cooler, and minor trimming possible to grill and 2 ears on bumper to fit the intercooler depending on your year. Bracket included to add a larger Tru-Cool transmission cooler under the Intercooler *recommended to replace the OEM*


*Include a Turbo, Wastegate, BOV and other options from the drop-down menus. For recommendations or questions on components, please feel free to e-mail us direct and ask at:
