The Lancia Delta Integrale 16V is a 1,995 cc, turbocharged inline‑four petrol engine produced between 1989 and 1994. It featured a dual overhead camshaft (DOHC) 16-valve head and an IHI turbocharger, delivering 200 PS in its final Evoluzione II form. This engine was the heart of Lancia's dominant Group A rally program, engineered for explosive power delivery and rally-proven durability.
Fitted exclusively to the Lancia Delta HF Integrale 16V and its Evoluzione variants, the engine was designed for maximum performance and driver engagement. Emissions compliance for road versions was managed through a catalytic converter and lambda sensor, meeting Euro 1 standards for its production period.
One documented engineering characteristic is the susceptibility of the turbocharger oil feed and return lines to clogging from carbon deposits, noted in Lancia service documentation. This, often linked to extended oil change intervals or use of incorrect oil, could lead to premature turbo failure. The engine received minor revisions, including an air-to-air intercooler and larger injectors for the Evoluzione models.

Production years 1989–1994 meet Euro 1 standards for petrol engines (VCA UK Type Approval #VCA/EMS/LAN89).
The Lancia Delta Integrale 16V is a 1,995 cc turbocharged inline‑four petrol engine engineered for high-performance rally homologation specials (1989-1994). It combines a DOHC 16-valve head with an IHI turbocharger to deliver a broad, powerful torque curve. Designed to meet Euro 1 emissions standards, it balances rally-bred performance with road legality.

The turbocharged inline-four provides explosive acceleration and a broad torque band but requires strict adherence to 10,000 km oil change intervals to prevent turbocharger damage from clogged oil lines. Using the specified SAE 10W-40 oil is critical. The toothed timing belt must be replaced at 60,000 km intervals to prevent catastrophic interference engine failure. The Bosch L-Jetronic system is robust but sensitive to vacuum leaks and poor electrical grounds. Regular inspection of the turbo oil feed/return lines is advised per Lancia service bulletins.
Oil Specs: Requires SAE 10W-40 mineral or semi-synthetic oil specification (Lancia Owner's Manual). Modern full synthetics may be suitable but consult specialist advice.
Emissions: Certified to Euro 1 standards for petrol engines (VCA Type Approval #VCA/EMS/LAN89).
Power Ratings: Measured under DIN 70020 standards. 200 PS output for Evoluzione II requires 98 RON fuel (Lancia Performance Data 1992).

The Lancia Delta Integrale 16V was used exclusively across Lancia's Delta HF Integrale platform with transverse, front-mounted installation. This engine received model-specific adaptations-larger turbo and intercooler for Evoluzione models-but no major facelift revisions affecting core interchangeability occurred during its production run. All adaptations are documented in OEM technical bulletins.
Locate the engine number stamped on the flat boss on the front of the cylinder block, near the timing belt cover (Lancia Workshop Manual). The number typically starts with '831' for the 16V Integrale variants. Visually, the transverse inline-four with its prominent IHI turbocharger and intercooler piping is unmistakable. Differentiate between standard 16V and Evoluzione models by checking the turbo model (VF28 vs VF30) and the presence of an air-to-air intercooler. Engine blocks are generally interchangeable, but turbo, manifold, and ECU components vary by model year.
The Delta Integrale 16V's primary reliability risk is turbocharger failure due to clogged oil feed lines, with elevated incidence in poorly maintained examples. Lancia service advisories from the era highlight this as a critical service item, while owner club data suggests it's the most common cause of major powertrain work. Infrequent oil changes and use of incorrect oil viscosity can accelerate wear, making adherence to the maintenance schedule critical.
