Twin Turbo Kit for Ford Mustang (1979-1993) 5.0L

Complete intercooled twin-turbo package for the Ford Mustang (1979–1993) with the 5.0L V8. It pairs two T3/T4 hybrid turbos with stainless tubular manifolds, a front-mount intercooler, dual oiling kits, oil cooler, boost controller, wastegates, blow-off valves, turbo timer and cooling fan 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 gain at a conservative 8–10 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. Piping is aimed at Fox-body 5.0L Mustangs; 351 swaps usually need extra fabrication.

Why this kit

• Twin T3/T4 hybrid turbos with .57 trim compressors and .50 / .63 A/R housings
• TIG-welded 321 stainless tubular manifolds with 1 5/8" primaries, support brackets and T3 flanges
• Front-mount intercooler, oil cooler, full piping kit, dual oiling kits and slim cooling fan
• Boost controller, wastegates, blow-off valves, turbo timer and catch can included

Package Includes

• (2) T3/T4 hybrid turbochargers with oil fitting gaskets and mounting studs
• (2) TIG-welded 321 stainless tubular turbo manifolds with full install hardware
• (1) Front-mount aluminum intercooler (3" cold outlet, 2.25" hot inlets)
• (1) Oil cooler kit
• (1) Aluminum intercooler piping kit with mandrel bends, 4-ply silicone couplers and T-bolt clamps
• (2) Turbo oil line kits: high-strength feed lines, high-temp 550 psi returns, T-fittings, gaskets and hardware
• (1) Manual boost controller with install kit
• (1) Slimline cooling fan
• (1) Electronic turbo timer
• (1) Oil catch can
• Wastegates and blow-off valves as shown in the package photos

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 per turbo / up to about 1000 hp twin with a built engine and supporting mods — not a stock-car dyno result. Plan on about 8–10 psi on a healthy stock engine with a proper tune

Exact Fitment — Ford Mustang

• 1979–1993 Ford Mustang with the 5.0L V8
• Piping is specific to Fox-body 5.0L Mustangs; other small-block swaps are up to the installer
• Chassis-specific downpipe and exhaust beyond the turbo flange are not included
• Intercooler piping may need trimming per chassis and accessory layout

Not Included

• Chassis-specific downpipe and exhaust beyond the turbos
• Larger injectors, fuel pump and ECU tune (required on fuel-injected cars)
• 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 piping around the Fox-body bay
• Oil return must drain by gravity; prime the turbos with oil before first start and check for leaks
• Works with fuel injection or carbureted setups when fueling is upgraded for boost
• Keep boost near 8–10 psi until fuel and tune are upgraded, and let the turbo timer handle cool-down

FAQs

Is this the same as the single-turbo hot-parts kit? No. This is a full twin-turbo intercooled package with turbos, manifolds, intercooler, oil cooler and supporting parts.

How much power will it make? A healthy stock engine at about 8–10 psi with a proper tune is the street baseline. Around 1000 hp is a twin 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 fueling upgrades, a tune on EFI cars, downpipes and some pipe fitting.
