The VTEC oil pressure solenoid and its screen can clog or fail, preventing VTEC engagement. On the B18C5 this is especially problematic given the high-rpm nature of the engine. Low oil pressure, dirty oil, or infrequent oil changes accelerate failure. A P1259 code is the classic indicator.

Timing Belt Failure Risk€300-800 · 100,000-160,000 kmHIGH
The B18C5 uses a rubber timing belt that is interference-spec — a belt snap means catastrophic valve-to-piston contact. On 20+ year old examples, many belts are past service life by age alone regardless of mileage. Full kit replacement including water pump and tensioner is essential.
Unknown service history
Belt cracking or glazing visible on inspection
Ticking from front of engine
Engine won't start after snap
DIY: Moderate
SRS / Airbag Control Unit Failure€200-600 · 100,000-200,000 kmMODERATE
NHTSA complaints document SRS warning light illumination caused by failed SRS control units on 1997 Integra models. Given vehicle age, capacitors and connectors in the airbag module degrade, causing fault codes and potentially disabling airbag deployment.
NHTSA complaints note inoperative speedometers on 1997 Integra models. Common cause is a failed vehicle speed sensor (VSS) or instrument cluster circuit degradation due to age. May also affect other gauge functions.
Multiple NHTSA recalls cover aftermarket headlight and corner lamp assemblies sold for the DC2 Integra (1990–2001). These parts from various suppliers were found to be non-compliant. Many used DC2s have had lighting modifications — verify any replacement lighting is OEM or compliant aftermarket.

Buying Checklist
Verify timing belt replacement date and mileage — demand receipts; if unknown, budget for immediate replacement before driving
Scan for P1259 and all OBD codes, then test VTEC engagement personally above 5,500 rpm on a test drive
Check oil level and condition on the dipstick — dark, low, or milky oil signals neglect or head gasket issues
Inspect SRS warning light on startup and confirm it extinguishes; persistent SRS light means control unit replacement is needed
Examine all exterior lighting for aftermarket fitment that may be subject to NHTSA recall — check for compliance markings
Assess overall maintenance history critically: the B18C5 is frequently modified or tracked, so look for signs of hard use, engine modifications, or accident damage in the engine bay

Buying Advice
The B18C5-powered DC2 Integra Type R is one of Honda's most celebrated engines, genuinely capable of high mileage when maintained with short oil change intervals and timely timing belt replacements. However, the reality of the used market is that most surviving examples have been driven enthusiastically, modified, or tracked — making a clean, stock, well-documented car rare and worth paying a premium for. Prioritise full service history over low mileage alone, and budget immediately for a timing belt kit and VTEC solenoid service regardless of what the seller claims. Walk away from any car with an active SRS light, unknown oil history, or signs of engine bay modifications that weren't professionally executed.
