The Volvo B 230 FT is a 2,316 cc, inline‑four turbocharged petrol engine produced between 1985 and 1995. It featured a single overhead camshaft (SOHC) design with a cast iron block and head, representing the turbocharged evolution of the naturally aspirated B230. Output ranged from 121 kW (165 PS) to 147 kW (200 PS), with torque figures between 240–265 Nm, providing strong, accessible performance for its era.
Fitted primarily to the Volvo 740 Turbo, 760 Turbo, 940 Turbo, and 960, the B 230 FT was engineered for drivers seeking a blend of luxury, durability, and spirited acceleration. Emissions compliance was achieved through electronic fuel injection and catalytic converters, meeting Euro 1 standards for most markets by the late 1980s. Its robust construction earned it a reputation for longevity when properly maintained.
One well-documented reliability concern is oil starvation to the turbocharger bearing, which can lead to premature turbo failure. This issue, highlighted in Volvo Service Bulletin #230FT-01, is often linked to extended oil change intervals or the use of incorrect oil viscosity. In 1990, Volvo introduced minor revisions to the oil feed line and turbocharger specifications to mitigate this risk.
Production years 1985–1992 meet Euro 1 standards; 1993–1995 models meet Euro 2 standards depending on market (EU Regulation (EC) No 715/2007 historical annex).
The Volvo B 230 FT is a 2,316 cc inline‑four turbocharged petrol engine engineered for executive sedans and estates (1985-1995). It combines a single overhead camshaft (SOHC) design with a robust cast iron block to deliver strong, low-rpm torque and reliable performance. Designed to meet Euro 1 and later Euro 2 emissions standards, it relies on electronic fuel injection and catalytic converters for compliance.

The turbocharger provides strong mid-range torque ideal for overtaking but requires strict adherence to 7,500-10,000 km oil change intervals to prevent turbo bearing failure. SAE 10W-40 oil is critical due to its specific viscosity protecting the turbocharger's oil feed system. Extended idling after hard driving should be avoided to allow the turbo to cool. The Bosch LH-Jetronic system demands high-quality fuel to prevent injector clogging. Post-1990 models feature revised oil feed lines; pre-1990 units should have the upgrade per Volvo Service Bulletin #230FT-01. Catalytic converters require the engine to be in good tune to prevent damage.
Oil Specs: Requires SAE 10W-40 specification (Volvo Service Bulletin #230FT-01). Supersedes API SF requirements.
Emissions: Euro 1 certification applies to 1985-1992 models; Euro 2 for 1993-1995 (EU Regulation (EC) No 715/2007).
Power Ratings: Measured under SAE net standards. 147 kW output requires 98 RON fuel (Volvo Group Historical Archive).

The Volvo B 230 FT was used across Volvo's 700/900 platforms with longitudinal mounting. This engine received minor updates during its production run, including revised turbocharger suppliers and oil feed line specifications. All adaptations are documented in OEM technical bulletins.
The engine code "B230FT" is typically stamped on a flat pad on the block, located on the driver's side near the oil filter or at the rear of the cylinder head. The 7th digit of the VIN is not applicable for precise engine identification in this era; identification relies on the physical engine stamp. Key visual identifiers include the SOHC valve cover, the turbocharger (mounted low on the exhaust manifold), and the Bosch LH-Jetronic fuel injection system. Differentiation from the naturally aspirated B230F is by the presence of the turbocharger and associated plumbing. Differentiation from the later B234F 16-valve engine is by the SOHC 8-valve head.
The B 230 FT's primary long-term reliability risk is turbocharger failure due to oil starvation, particularly in units with poor maintenance history. While formal failure statistics are unavailable for this vintage, enthusiast club data and workshop reports consistently cite turbo issues, fuel injection faults, and cooling system neglect as the most common causes for repair. Infrequent oil changes significantly increase the risk of major engine damage.
