Turbo Kit for GMC Sierra Yukon (1999-2013) 4.8L 5.3L 6.0L 6.2L

Complete intercooled T4 turbo package for GMC Sierra / Yukon with the 4.8L, 5.3L, 6.0L and 6.2L V8s (1999–2013). It pairs a cast T4 manifold and driver-side manifold with a hybrid T3/T4 turbo, stainless crossover with wastegate flange, front-mount intercooler, oiling, boost controller, blow-off valve, turbo timer, battery relocation and fuel-system parts in one box. Most installs keep A/C and power steering, and it works with manual or automatic transmissions when the engine matches. Expect a solid street boost setup at a conservative 8 psi with a proper tune. The 750 hp figure is the hardware ceiling with a built engine, fueling and supporting mods, not a dyno result for a stock truck.

Exact Fitment — GMC Sierra / Yukon

• 1999–2013 GMC Sierra / Yukon with 4.8L, 5.3L, 6.0L or 6.2L V8
• One Make per listing — this product is GMC only
• Chassis-specific downpipe and exhaust beyond the turbo flange are not included — plan on fabricating or sourcing them
• Intercooler piping is universal and needs cutting and fitting per chassis

Not Included

• Chassis-specific downpipe and exhaust beyond the turbo
• Larger injectors, fuel pump and ECU tune (required)
• Clutch or transmission upgrade, boost gauge and wideband (unless listed above)
• 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 street cast, not equal-length tubular: stronger and more affordable, with a different spool character
• Oil return must drain by gravity; prime the turbo with oil before first start and check for leaks
• Blow-off valve flanges are installed at your discretion
• Keep boost near 8 psi until fuel and tune are upgraded, and let the turbo timer handle cool-down

FAQs

Does this fit GMC and Chevrolet 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 at about 8 psi with a proper tune is the street baseline. 750 hp is the hardware ceiling 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, a downpipe and some pipe fitting.
