What is the 1989-2002 Nissan Skyline Structural Rust: Strut Towers, Rear Arches, Sills and Boot Floor?
All three Skyline generations are now 24-37 years old and were built with minimal rustproofing, so corrosion in the front strut tower seams, rear wheel arches, sills, boot floor and chassis rails is the single biggest body concern on imports. Water gets past aging boot seals and… Repairs typically run $800-$6,000. Severity: high.
What is the 1989-2002 Nissan Skyline Ceramic Turbocharger Exhaust Wheel Failure?
Factory twin turbos on the GT-R (and the single turbos on RB20DET/RB25DET GTS-T models) use lightweight ceramic exhaust wheels for fast spool, but the brittle ceramic shears off the shaft with age, heat cycles, detonation, rev-limiter hits, or boost much above the stock ~0.9-1.1… Repairs typically run $1,500-$6,000. Severity: high.
What is the 1989-2002 Nissan Skyline Super HICAS Rear-Steer System Aging: Leaks, Solenoid Faults and Worn Ball Joints?
All performance Skylines of this era carry HICAS/Super HICAS four-wheel steering (hydraulic on R32, electric rack on R33/R34), and with age the rear rack seals leak, solenoids and the rear-toe control hardware fail, and the system's rear ball joints wear and introduce vague, wand… Repairs typically run $300-$1,800. Severity: medium.
What is the 1989-2002 Nissan Skyline Crank Angle Sensor (CAS) Failure: Hot Stalling and No-Start?
The optical crank angle sensor driven off the exhaust camshaft on RB20/RB25/RB26 engines degrades with age and heat, causing intermittent loss of timing signal. The classic pattern is an engine that runs fine cold, then cuts out, backfires or stalls as it heats up and refuses to… Repairs typically run $150-$500. Severity: medium.
What is the 1989-2002 Nissan Skyline ATTESA E-TS Hydraulic Pump and Nitrogen Accumulator Failure?
The GT-R's (and GTS-4's) ATTESA E-TS all-wheel-drive system uses an electric hydraulic pump and a nitrogen-charged accumulator mounted near the fuel tank to pressurize the front-drive transfer clutch.

The classic result is a misfire that appears only… Repairs typically run $250-$900. Severity: medium.
