Turbo Kit for GMC Sierra Yukon (2014-2023) 5.3L 6.2L

Complete twin-turbo intercooled package for GMC Sierra / Yukon (2014–2023) with the 5.3L and 6.2L V8s. It pairs two stainless tubular manifolds with two T3/T4 hybrid turbos, dual internal wastegates, a front-mount intercooler, dual oiling kits, boost controller, blow-off valve, turbo timer, battery relocation, boost gauge and fuel-system parts in one box. Most installs keep A/C and power steering. On a stock truck, plan on a conservative street tune with supporting fuel and calibration. Big twin HP numbers are a hardware ceiling with a built engine and supporting mods, not a dyno result for a stock truck. Engine family references: Gen 5 small-block / L83 / L86 (codes belong in the bay, not the title).

Turbocharger Specs

• Type: T3/T4 hybrid each, wet-float bearings, balanced
• Compressor: .57 trim wheel, .50 A/R housing, 3" inlet, 2" outlet
• Turbine: .63 A/R housing via V-band to T3 adapters
• Oil inlet: 1/8" NPT
• Hardware ceiling over 450 hp per turbo with a built engine and supporting mods — not a stock-truck dyno result. Plan on low boost with a proper tune on a healthy stock engine

Exact Fitment — GMC Sierra / Yukon

• 2014–2023 GMC Sierra / Yukon with 5.3L or 6.2L V8
• One Make per listing — this product is GMC only
• Not for 1999–2013 trucks — those have their own listings
• Chassis-specific downpipes and exhaust beyond the turbo flanges are not included
• Intercooler piping is universal and needs cutting and fitting per chassis

Not Included

• Chassis-specific downpipes and exhaust beyond the turbo flanges
• Larger injectors, fuel pump and ECU tune (required)
• Clutch or transmission upgrade and wideband
• Oil-pan return bung if your setup needs one

Installation Notes

• Professional installation strongly recommended. Expect cutting and fitting of the universal piping
• The manifolds are stainless tubular with V-band turbo adapters for clocking
• Oil return must drain by gravity on both turbos; prime each turbo with oil before first start and check for leaks
• Blow-off valve flanges are installed at your discretion
• Keep boost conservative until fuel and tune are upgraded, and let the turbo timer handle cool-down

FAQs

Does this fit Chevrolet and GMC on one order? No. Chevrolet and GMC each have their own listing for this platform.

How much power will it make? A healthy stock engine with a proper tune at low boost is the street baseline. Twin hardware can support far more with a built engine and full supporting mods.

Can I keep A/C and power steering? Most installs keep both; confirm clearance during mock-up.

Manual or automatic? Fits either when the engine matches.

Is it plug-and-play? No. You still need injectors, a fuel pump, an ECU tune, downpipes and some pipe fitting.
