Turbo Kit T70 T4 For Silverado Sierra Turbocharger
Comprehensive upgrade kit designed for V8 LS engines, including mandrel-bent piping, a high-flow turbo, and essential hardware. Constructed from stainless steel, this kit emphasizes durability and corrosion resistance for long-lasting performance. Precision engineering ensures optimal airflow and boost, contributing to noticeable horsepower gains. Suitable for 4.8L, 5.3L, and 6.0L LS setups found in Silverado and Sierra models, particularly those built after 1999.
MMI Speed Shop Turbo Parts Kit for Silverado/Sierra LS
This complete turbo kit is tailored for Chevy Silverado and GMC Sierra LS engines (4.8/5.3/6.0 V8) from 1999 to present. The package includes cast manifolds with thick head flange passenger T4 and driver-side manifolds, featuring larger ports to improve exhaust flow and durability. A TIG-welded crossover and stainless steel clamp enhance heat resistance and longevity, supporting steady boost and reliable operation in real-world conditions.
T4 Cast Turbo Manifold Flange 2.5″ Replacement
This flange serves as a direct replacement for the Chevy Silverado/Avalanche manifold setup (1999–2013), aligning with 2.5″ exhaust components. OE part references (0023256) support compatibility, helping maintain proper exhaust flow and fitment. It offers a straightforward upgrade path for turbo plumbing and is designed to integrate with existing LS exhaust manifolds to support turbocharged configurations.
ICT Billet LS Twin Turbo Oil Feed Adapter Plate
This billet aluminum plate seals off the oil port in the oil pan above the filter and provides two 1/8″ NPT ports for sensors or turbo oil feed lines. Compatible with most LS oil pans (except certain front-sump, dry-sump LS variants). Manufactured in Wichita, Kansas, this plate supports flexible oil system integration while offering heat resistance and durability essential for turbocharged LS builds.
LS Oil Barbell 3 O Ring Design
This barbell is designed for Gen GM III & IV engines, covering a wide range of LS models including LQ4, LQ9, L92, L99, L33, LS1, LS3, LS2, LS6, and LSX variants. It features three O-ring seals for robust oil sealing, reducing leaks and maintaining oil pressure during turbo operation. Replacement OEM reference 12573460 allows direct swap for improved performance and longer service life when upgrading LS turbo kits.
Buying Guide: Key Considerations For LS Turbo Kit Purchases
When evaluating LS turbo kit options, consider these factors to ensure you meet your performance goals while maintaining reliability and project scope.
Compatibility And Vehicle Application
Confirm engine displacement, generation (Gen III or Gen IV), and model year compatibility with your Silverado or Sierra. Some kits are tailored for specific LS families and may require bespoke exhaust plumbing or tuning to achieve the target boost safely.
Kit Completeness
Look for a complete kit that includes intake piping, intercooling (if applicable), exhaust manifolds or headers, hardware, clamps, and reducers. A well-rounded kit minimizes the need for additional purchases and simplifies installation.
Materials And Durability
Durable materials such as stainless steel and forged billet components deliver long-term reliability in the heat and stresses of forced induction. High-quality welds and corrosion resistance are important for street-driven and track-ready builds alike.
Hardware And Fitment
Assess the fitment of flanges, crossover pipes, and oil supply lines. Adapters and plates that integrate with OEM components reduce the risk of leaks or clearance issues with steering, suspension, or accessory belts.
Oil Delivery And Pressure Management
A reliable oil feed solution is critical for turbo longevity. Ensure there are compatible oil feed provisions and seals that prevent leaks while maintaining stable pressure under boost.
Tuning And Support
Consider the availability of tune support, required ECU calibration, and whether aftermarket software or professional dyno tuning is recommended. Some kits pair with specific engine management platforms for smoother, safer power delivery.
Warranty And Support
Check manufacturer warranties, return policies, and the availability of replacement parts. Given the complexity of turbo systems, access to good support can reduce downtime and frustration during installation.
In evaluating these LS turbo kit options, you can balance full kit completeness, durable construction, and targeted LS engine compatibility to select a solution that matches your goals—whether it’s a weekend warrior, a street racer, or a project vehicle built for consistent performance gains.
