Turbo Kit for Chevrolet C1500 Tahoe Blazer (1988-1998) 5.0L 5.7L

Complete twin-turbo intercooled package for Chevrolet C1500 / Tahoe / Blazer (1988–1998) with small-block V8s (5.0L / 5.7L typical). It pairs two stainless tubular manifolds with two T3/T4 hybrid turbos, dual internal wastegates, a front-mount intercooler, dual oiling kits, oil cooler, boost controller, dual blow-off valves, turbo timer 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. On a stock motor, plan on a low-boost street tune around 8–10 psi. Big twin HP numbers are a hardware ceiling with a built engine and supporting mods, not a dyno result for a stock truck.

Exact Fitment — Chevrolet C1500 / Tahoe / Blazer

• 1988–1998 Chevrolet C1500 / Tahoe / Blazer with small-block V8 (common 5.0L 305 and 5.7L 350)
• One Make per listing — this product is Chevrolet only
• 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, boost gauge 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 welded support brackets
• 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 near 8–10 psi 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 at about 8–10 psi with a proper tune 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.
