1991 Lancia Delta HF Integrale 559BHP 16V Up for Auction!

Transformed by Lancia Maxi in Bulgaria in 2017, this rally-inspired machine features custom fiberglass bodywork, a reinforced chassis, and a heavily upgraded 2.0-liter turbocharged inline-four. With cutting-edge performance enhancements, a motorsport-grade interior, and an aggressive stance, this Delta HF Integrale is built to dominate both the road and the track. Now, this incredible build is up for auction on Bring a Trailer, offering enthusiasts a rare opportunity to own a one-of-a-kind rally icon.

A Bespoke Fiberglass Widebody Conversion

Ditching its factory panels, this Delta HF Integrale wears a fully custom fiberglass body kit from Lancia Maxi. The transformation includes a vented Evo-style hood, reworked fender flares, a modified roof, and an aerodynamic carbon-fiber rear diffuser. The Group A-style mirrors, a black front lip spoiler, and an adjustable roof-mounted wing further enhance its aggressive rally aesthetic. Lexan windows replace the factory glass for weight savings, and aftermarket hood pins secure the front and rear hatches. Painted in a striking shade of red, this build is designed to turn heads while maintaining a functional motorsport-inspired look.

Sitting on lightweight 17-inch OZ Racing Superleggera wheels wrapped in fresh 245/40 Kumho Ecsta V730 rubber, this Delta HF Integrale is engineered for maximum grip. The braking system is equally impressive, featuring Brembo four-piston front calipers clamping onto 330mm cross-drilled and vented rotors. At the rear, two-piston Brembo calipers pair with 280mm solid discs. A high-performance AP Racing tandem master cylinder, a dash-mounted brake bias adjuster, and the removal of the ABS system ensure precise stopping power tailored for high-speed performance.

Track-Ready Suspension and Steering Enhancements

This Lancia Delta HF Integrale isn’t just about power—it’s built to handle. It features KW adjustable coilovers, upgraded front control arms with uniball joints, and adjustable torsion bars for optimal suspension tuning. A quick-ratio steering rack, assisted by a high-flow hydraulic pump, provides razor-sharp turn-in response, making it an absolute weapon in the corners.

Step inside, and it’s clear this Delta HF Integrale was built with performance in mind. A multi-point roll cage from UK-based Custom Cages reinforces the stripped-down cabin, which is finished in white for a true motorsport aesthetic. Fixed-back GP-Race and Sparco bucket seats, paired with a six-point racing harness for the driver and a three-point belt for the passenger, ensure safety during high-speed runs. A MOMO Corse quick-release steering wheel sits ahead of Veglia gauges, including a 9,000-rpm tachometer, a 240-km/h speedometer, and essential readouts for boost, oil pressure, temperature, and voltage. Carbon-fiber dash inserts house a push-button ignition and an IMYAQA-controlled intercooler water sprayer system, while a Greddy Profec B-spec II boost controller sits mounted to the steering column. A fire extinguisher, an ATL fuel cell, and three Bosch high-flow fuel pumps complete the track-focused cockpit.

Under the hood, this Delta HF Integrale features a fully built 2.0-liter DOHC inline-four sourced from an Evo 1 model. Extensively modified to handle serious boost, the engine features:

• JE Pistons forged pistons
• Upgraded camshafts
• Balance shaft delete
• Lightweight timing components
• ARP cylinder head fasteners
• Custom aluminum intercooler with water spray system
• High-capacity aluminum radiator
• Garrett GTX turbocharger with a heat blanket
• Prospeed Autosports fuel rail with Siemens injectors
• Bosch 120-amp alternator
• Bonalume Power-Pop blow-off valve
• Custom air intake with an ITG Megaflow filter
• Reinforced engine mounts
• MoTeC M4 engine management

A Braille AGM battery was installed in February 2025 to keep up with the car’s electrical demands. On the dyno, this beast puts down an impressive 559 horsepower at the wheels, making it a true force to be reckoned with.

Power is sent to all four wheels via a five-speed manual transaxle rebuilt with a Bacci Romano dog-engagement kit. A Ferguson viscous coupling center differential and a Torsen limited-slip rear differential ensure that the Delta HF Integrale maintains its legendary all-wheel-drive traction. An AP Racing four-puck clutch and an upgraded aluminum driveshaft ensure smooth and reliable power delivery, whether on the road or the racetrack.
