Turbo Kit for Chevrolet Cobalt (2005-2009) 2.2L 2.4L

Complete intercooled T3/T4 turbo package for the Chevrolet Cobalt (2005–2009) with the 2.2L / 2.4L four. It pairs a stainless tubular manifold with a hybrid turbo, front-mount intercooler, piping, boost controller, turbo timer, stainless downpipe, heat wrap and intake filter in one box. Most installs keep A/C and power steering, and it works with manual or automatic transmissions when the engine matches. About +50–100 hp on a healthy stock engine at 8 psi with a proper tune. 485+ hp is the hardware ceiling with a built engine and supporting mods, not a dyno result for a stock car. Engine family reference: LE5 / L61 as equipped.

Exact Fitment — Chevrolet Cobalt

• 2005–2009 Chevrolet Cobalt with the 2.2L or 2.4L four
• A stainless turbo manifold-only listing may already exist for Cobalt — this is the complete turbo kit
• Intercooler piping is universal and needs cutting and fitting per chassis

Not Included

• Larger injectors, fuel pump and ECU tune (required)
• External wastegate / blow-off valve kits (not in this package — plan boost control during install)
• Clutch 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
• Oil return must drain by gravity; prime the turbo with oil before first start and check for leaks
• Keep boost near 8 psi until fuel and tune are upgraded, and let the turbo timer handle cool-down

FAQs

Is this just a manifold? No. This is the complete turbo kit with turbo, intercooler, piping and accessories.

How much power will it make? About +50–100 hp on a healthy stock engine at 8 psi with a proper tune. 485+ 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 and some pipe fitting.
