Features & Benefits of the Huron Speed Truck V3 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 44mm flange to control boost. No need to worry about boost creep issues!

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

*(2) bellows are used in the crossover pipe to allow easy alignment, seal, and connection to the manifolds. With one bellow per side it will allow easier alignment and install, as well as less stress on the system and the bellows = longer life!

*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.

*4″ Downpipe option available to bolt up to larger Mid-frame PT88 turbo and now also Borg Warner S400 turbos

*Cold Side Tubing made from Aluminum provide a clean filterd air intake for the turbocharger as well as intercooler and tubing to fit 03-07 trucks to reliable make more power with more boost utlizing cooled air from the intercooler!

*Cold Side Tubing features a 50mm BOV flange and Threaded IAT Sensor Bung with a large 4″ Thick Intercooler


**Retains factory Air Conditioning, requires some bending/massading to OEM hardline near the accumulator OR add on our Custom A/C Line for better clearance around your downpipe!

**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.

**Flex section on passenger side will not clear 4L80 transmission. Trimming of transmission ear required on 4L80 transmissions only.


*Include a Turbo, Wastegate, and BOV at a big discount to make your hotside kit more complete. For recommendations or questions on components, please feel free to e-mail us direct and ask at:
