Turbo Kit for Pontiac Sunfire (1996-2000) 2.4L

Complete intercooled T3/T4 turbo package for the Pontiac Sunfire (1996–2000) with the 2.4L four. It pairs a stainless tubular manifold with a hybrid turbo, internal wastegate, 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 about a solid street gain at a conservative 8 psi with a proper tune. Bigger HP numbers are a hardware ceiling with a built engine and supporting mods, not a dyno result for a stock car. Engine code reference: LD9.

Turbocharger Specs

• Type: T3/T4 hybrid, wet-float bearings, balanced
• Compressor: .57 trim wheel, .50 A/R housing, 3" inlet, 2" outlet
• Turbine: .63 A/R housing
• Oil inlet: 1/8" NPT
• Hardware ceiling over 450 hp with a built engine and supporting mods — not a stock-car dyno result. Plan on about 8 psi on a healthy stock engine with a proper tune

Exact Fitment — Pontiac Sunfire

• 1996–2000 Pontiac Sunfire with the 2.4L twin-cam four
• Not for 2.2L Sunfire — that engine has its own listing
• Chassis-specific downpipe and exhaust beyond the turbo flange are not included
• 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 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
• 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 a 2.2L Sunfire? No. This listing is 2.4L only. The 2.2L kit is separate.

How much power will it make? A healthy stock engine at about 8 psi with a proper tune is the street baseline. Over 450 hp is a 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.
