Acura Integra: generations, trims & engines

A trim can keep the same engine code while its output or electronics change. Specification versions stay separate below. These sourced groups do not identify the trim of every EPA fuel-economy configuration. Open the grouped Integra reference ↗

Generation 2 1990–1993

U.S. model years. Detailed trim coverage is stated on each card; it may cover only part of this generation.

INTEGRA / United States

LS 1990–1993

Engine code B18A1

Specification versions
Model years	Power	Torque
1990–1991	130 hp≈ 96.9 kW	121 lb-ft
1992–1993	140 hp≈ 104.4 kW	126 lb-ft

ECU / OBD generation: Not independently verified

Same engine code, separate specification versions. Original catalog OBD labels are inconsistent; its 1992–1993 torque also differs from Acura's chronology. Original records are preserved.

Sources and scope

Acura generation / specification chronology
NHTSA code evidence: schemas 11136, 11046, 11045, 11044

Engine-code identity links do not establish interchangeability with every legacy variant. Original source configurations and conflicting legacy values remain available separately.

INTEGRA / United States

RS 1990–1993

Engine code B18A1

Power rating not established for this trim by the selected rating source.

ECU / OBD generation: Not independently verified

NHTSA engine/model and RS trim conditions are retained as evidence. The cited Acura LS/GS rating table is not silently generalized to RS.
