Turbochargers Kits

Updated May 12, 2026

For the broader buying-decision context on aftermarket replacement turbos by chassis lane, see the Read the cross-engine roundup — which kit fits the buyer's engine determines almost everything else.

What Comes in the Box of a Complete Kit

A complete OEM-spec replacement kit for a Cruze 1.4L GT1446V or Cummins 6.7L HE351VE ships six things: the turbo unit itself, exhaust manifold gaskets, oil supply and return gaskets, coolant fitting gaskets, manifold-to-turbo studs (typically 4-6 per turbo), and the wastegate actuator pre-installed for fixed-geometry frames or pre-mounted but calibration-required for variable-geometry frames.

Premium kits add a turbo-to-downpipe gasket, V-band clamps where the OE chassis uses them, and copper crush washers for the oil fitting threads. Budget kits at the same headline price often skip the manifold studs and the downpipe gasket — these are the two pieces buyers learn about at install time when the kit lands and the parts counter is closed. Listings that show only the turbo unit and a generic "gaskets included" tag are the worst offenders. Listings that itemize each gasket and stud separately are the buyer's safety net.

The wastegate actuator is the highest-stakes component in the kit beyond the turbo itself. On fixed-geometry applications (Cruze 1.4L GT1446V, Ford EcoBoost 2.0L K03), the actuator ships pre-installed and pre-calibrated; the buyer mounts the turbo and the actuator is ready to operate on factory boost pressure. On variable-geometry diesel applications (Cummins 6.7L HE351VE / HE300VG, Ford 6.7L Power Stroke GT3782VAS / GT3788LVA), the actuator ships pre-installed but the position-encoder values must be written to the ECM after install via a dealer-spec scan tool. Some Cummins-segment kits ship the actuator separately to enable the actuator-only repair path described in the Read the four-stage repair decision guide.

OE-Replacement Kits vs Universal Kits

OE-replacement kits (Cruze 1.4L 55565353, Cummins 6.7L HE351VE) bolt onto the factory exhaust manifold and downpipe with zero fabrication. Universal kits (T3 / T4 / GT45 frame format) require the buyer to fabricate the exhaust manifold and intake plumbing themselves — typically 8-20 hours of fab work plus parts.

OE-replacement kits are formatted by chassis. The Cruze 1.4L kit fits the LUJ / LUV Ecotec mounting pattern exactly; bolt the turbo to the manifold with the supplied studs, connect the oil and coolant lines with the supplied gaskets, plug in the wastegate actuator harness, install the downpipe with the supplied V-band, done. The Cummins 6.7L kit fits the HE351VE / HE300VG mounting pattern; the same OE-format swap on a different chassis. The kit listings cross-reference OE part numbers explicitly (55565353 / 781504 / 667-203 for Cruze; 5494878RX / 5354495 / 6411490 for Cummins) and the install fits the OE service manual procedure exactly.

Universal kits ship in performance-format flanges (T3 / T4 / T04E / GT45 with V-band downpipe options) and target the aftermarket build category where the buyer is fabricating the exhaust manifold, intake plumbing, and oil supply / return lines from scratch. The kit includes the turbo plus the wastegate (often external instead of integral), oil fitting hardware, and a generic gasket set. It does NOT include a chassis-specific exhaust manifold, downpipe, or charge pipe — those are the buyer's fabrication scope. Universal kits are the wrong call for OE-replacement work on a stock chassis; the bolt pattern will not match and the install turns into a 12-hour fabrication exercise.

The Install-Completeness Checklist

Before ordering any complete turbocharger kit, run the listing through a four-item completeness checklist: OE cross-reference, gasket-kit inventory, hardware kit, and actuator status. A listing that documents all four is safe; a listing missing one is a budget tier with hidden install cost.

OE cross-reference. For Cruze 1.4L, the listing should name 55565353 / 781504 / 667-203 / GT1446 explicitly. For Cummins 6.7L, it should name 5494878RX / 5354495 / 6411490 / HE351VE / HE300VG explicitly. For Ford EcoBoost 2.0L, it should name CJ5Z6K682-X / 53039880271 explicitly. A listing that says "fits 2014-2018 Ram 2500 with 6.7L Cummins" but does not cross-reference OE part numbers is hiding ambiguity that the buyer will discover at install.

Gasket-kit inventory. The listing should itemize the gaskets included: exhaust manifold to head, manifold to turbo, turbo to downpipe, oil supply, oil return, coolant fittings (where applicable). A listing that says "gasket kit included" but does not itemize is hiding a missing piece. Hardware kit. Manifold-to-turbo studs (always required for Cruze 1.4L where OE studs typically snap), V-band clamps for downpipe (Cummins 6.7L), copper crush washers for oil fittings. Actuator status. Pre-installed and pre-calibrated for fixed-geometry; pre-installed but calibration-required after fitment for variable-geometry diesel applications.

Kit vs Rebuild — Two Different Decisions

A replacement kit ($150-$2,500 depending on chassis) ships a complete new or remanufactured turbocharger plus install gaskets. A rebuild kit ($80-$600) ships only the wear components — bearing cartridge, balanced wheels, oil seals, snap rings, shaft bushings — to refurbish the existing turbo in place at a specialty shop with a balance machine.

Replacement kit format. Cruze 1.4L complete kits run $150-$400 for budget-tier (A-Premium, Ingkan, Filterup, Autobaba, Donpida, Tekkoauto) and $400-$700 for OE-Garrett or premium rebuilder tier. Cummins 6.7L complete variable-geometry turbos run $1,200-$2,500. Performance aftermarket complete kits run $300-$3,500 depending on frame size, bearing type, and brand tier. The complete-replacement decision is right when the existing turbo housing is cracked, overspun, oil-contaminated, or carbon-fouled past the rebuild threshold.

Rebuild kit format. Bearing housing cartridge, balanced compressor and turbine wheel components, oil seals, snap rings, shaft bushings. Cruze 1.4L rebuild kits run $80-$200; Cummins 6.7L rebuild kits run $150-$400; performance aftermarket rebuild kits run $200-$600. The rebuild decision is right when the existing housing is sound (no cracks, no over-temperature discoloration) and only the rotating assembly is worn. Rebuilds usually require a specialty turbo shop because the balance discipline cannot be done with hand tools — the shaft must be balanced to ISO-grade tolerances on a dedicated machine. DIY rebuilds on a stock-replacement turbo are rarely cost-effective; specialty rebuilds on a premium aftermarket turbo (Garrett GTX, Precision PT, BorgWarner EFR) often are.

Install Cost Reality — DIY vs Shop

The kit purchase price is roughly half the total cost in most install scenarios. A $250 budget kit on a Cruze 1.4L typically lands at $400-$600 total cost after add-on parts (replacement PCV valve, fresh oil and coolant, new air filter), shop labor (2-4 hours at $120-$180/hr if the buyer is not DIY), and post-install diagnostic scan ($50-$100 if a code clear or recalibration is needed).

Heavy-duty diesel install scales up. A $1,500 Cummins 6.7L complete kit typically lands at $2,000-$3,500 total with the calibration scan tool visit ($150-$300 at a dealer or independent diesel shop), the fresh ECM oil change, and the supplementary parts (charge pipes, intercooler hoses) that should be replaced at the same time. Performance aftermarket builds scale further — a $1,200 Precision PT6266 kit on a Honda B-series turbo build typically lands at $4,000-$8,000 total once the custom exhaust manifold, intercooler, fuel system upgrade, and standalone engine management are included.

Turbocharger Kit Decision Questions

What is included in a turbocharger replacement kit?

A complete OE-replacement turbocharger kit ships the turbo unit itself plus exhaust manifold gaskets, oil supply and return gaskets, coolant fitting gaskets, manifold-to-turbo studs (when the OE chassis snaps them off on disassembly), and the wastegate actuator pre-installed. Premium kits add a turbo-to-downpipe gasket, V-band clamps where applicable, and copper crush washers. Budget kits at the same price point often skip the manifold studs and downpipe gasket — the buyer learns at install time when the cheaper kit lands with a $40 stop at the parts counter.

How can you tell if a turbocharger kit is complete for a specific vehicle?

Check the listing for explicit OE cross-references and a gasket-kit inventory. A complete Cruze 1.4L kit cross-references OE 55565353 / 781504 / 667-203, includes a gasket kit for exhaust manifold + oil lines + coolant lines, and lists the manifold studs explicitly. A complete Cummins 6.7L kit cross-references OE 5494878RX / 5354495 / 6411490 and includes the variable-geometry actuator wiring harness. Listings that show only the turbo and a vague "gaskets included" tag are usually missing two or three install-required pieces.

Are universal turbocharger kits worth it?

For aftermarket performance builds where the buyer is fabricating the exhaust manifold, intake plumbing, and oil supply / return lines anyway, universal kits (T3 / T4 / T04E / GT45 frame format with V-band or T3 flanges) are the right format. For OE-replacement work on a stock chassis, universal kits are the wrong call — the bolt pattern and flange geometry will not match the factory exhaust manifold or downpipe, and the install turns into a 12-hour fabrication exercise instead of a 4-hour swap.

How much does a complete turbocharger kit cost?

For OE-replacement applications on high-volume passenger chassis: $150-$700 (Cruze 1.4L, Ford EcoBoost 2.0L). For heavy-duty diesel applications: $700-$2,500 (Cummins 6.7L actuator-only path, $200-$700; complete variable-geometry turbo, $1,500-$2,500). For performance aftermarket: $300-$3,500 depending on frame size, journal vs ball-bearing, and brand tier. Premium rebuilder packages (Fleece Performance, BD Diesel, Industrial Injection, KC Turbos) sit at the high end of the OE-replacement category and overlap with mid-tier aftermarket pricing.

Do turbocharger kits include the wastegate actuator?

Most factory-replacement kits ship with the wastegate actuator pre-installed and pre-calibrated. The exception: variable-geometry diesel applications (Cummins 6.7L HE351VE / HE300VG, Ford 6.7L Power Stroke GT3782VAS), where the calibration step requires a dealer or shop scan tool to write the new actuator's position-encoder values to the ECM after install. Some kits provide the actuator separately as a sub-component to enable the actuator-only repair path when the underlying turbo mechanical condition is still serviceable.

What is the difference between a turbo kit and a rebuild kit?

A turbo replacement kit ships a complete new or remanufactured turbocharger plus install gaskets. A turbo rebuild kit ships only the wear components needed to refurbish an existing turbo in place: bearing housing cartridge, compressor and turbine wheel balance components, oil seals, snap rings, and shaft bushings. Rebuild kits are $100-$400 versus $300-$2,500 for a complete replacement. The right pick depends on whether the existing turbo housing is sound (rebuild kit wins) or already cracked / overspun / contaminated (replacement kit wins).

Can a turbocharger kit be installed DIY?

A capable DIY mechanic with a torque wrench, an oxy-acetylene torch (for snapped manifold studs), copper anti-seize, and a service manual can install most OE-replacement kits on passenger-car chassis in 4-8 hours. Heavy-duty diesel kits (Cummins 6.7L, Ford 6.7L Power Stroke) typically need 6-12 hours plus the calibration scan tool. Performance aftermarket kits on a custom build can extend to 20-40 hours of fabrication work. The decision turns on whether the buyer is comfortable with exhaust-manifold removal, fluid-line replacement, and a dealer scan tool visit if the application is variable-geometry.
