The Lancia 828 B4.000 is a 1,995 cc, inline‑four petrol engine produced between 1985 and 1994. It features a twin‑cam (DOHC) design and electronic fuel injection, delivering a balance of performance and refinement for its era. The engine's aluminium cylinder head contributes to weight savings and improved thermal efficiency.
Fitted primarily to the Lancia Thema 8.32 model, the 828 B4.000 was engineered to offer a sporting character derived from Ferrari's 308/328 V8. E…
Production years 1985–1994 meet the emissions standards applicable in their respective markets during that period (EU Regulation (EEC) No 83/1985, subsequent amendments).
The Lancia 828 B4.000 is a 1,995 cc inline‑four petrol engine engineered for premium sedans (1985-1994). It combines a Ferrari-derived DOHC cylinder head with electronic fuel injection to deliver a high-revving, sporting character. Designed to meet the emissions regulations of its production era, it prioritized performance within the technological constraints of the time.

The Lancia 828 B4.000 was used exclusively in the Lancia Thema platform with longitudinal mounting and was not licensed to other manufacturers. This engine was a unique feature of the Thema 8.32 variant, with no platform-specific adaptations beyond its standard installation. All technical details are documented in Lancia service literature.
The 828 B4.000's primary reliability consideration is the cost and complexity of maintaining its Ferrari-derived valvetrain. While mechanically robust when serviced correctly, neglecting the timing belt or valve adjustments can lead to expensive failures. Sourcing original parts for the fuel injection and ignition systems can also be challenging due to the model's age and low production volume.

The most common questions about engine codes, what they mean, how to find them and how this database works
It can be very reliable with meticulous, specialist maintenance. Its Achilles' heel is the timing belt – failure is catastrophic. The complex valvetrain also demands expert care. If serviced correctly with genuine parts, it's a robust and rewarding engine.
The most critical issue is timing belt failure. Other common problems include worn valve shims causing noise, ageing fuel injection sensors leading to running issues, and oil leaks from various gaskets and seals. Electrical gremlins are also common in older vehicles.
This engine was used exclusively in the Lancia Thema 8.32, produced from 1985 to 1992. It was never fitted to any other Lancia model or licensed to another manufacturer, making it a unique and sought-after powerplant.
Significant tuning is complex and expensive due to its bespoke nature. Minor gains are possible with a remap (if ECU allows), performance exhaust, or improved air intake. However, its value lies in its originality and unique Ferrari-derived character, not tunability.
Fuel economy is not its strong suit. Expect around 12-14 L/100km (20-17 mpg UK) in mixed driving. Its 2.0L displacement and high state of tune prioritize performance over efficiency, typical for a sports sedan of its era.
Yes, absolutely. This is its most critical characteristic. If the timing belt breaks or jumps, the pistons will collide with the open valves, causing severe and expensive internal engine damage. Strict adherence to the replacement schedule is non-negotiable.
Lancia originally specified SAE 10W-40 mineral or semi-synthetic oil. Today, a high-quality 10W-40 or 5W-40 semi-synthetic or full synthetic oil meeting ACEA A3/B4 specifications is recommended for better protection, especially for infrequently driven examples.
