Common Drivetrain

2nd Gear Synchro Wear (5-Speed Manual)

Symptoms

Grinding or crunching when shifting into 2nd gear, particularly on quick downshifts from 3rd. May also grind on fast upshifts from 1st. The problem worsens with use.

Cause

Second gear takes the most abuse in normal driving, every stop-start cycle involves a 1st-to-2nd shift. In a Silvia that has been drifted, the 2nd gear synchro bears even more punishment: clutch kicks, quick shifts, and abrupt downshifts all accelerate synchro wear. The 5-speed gearbox in the S13 and S14 is adequate but not over-built, and the synchro rings are a known wear item.

Fix

Gearbox rebuild with new synchro rings, bearings, and seals.

Cost: $1,000-2,000 for parts and labour.

A used gearbox from a wrecker is an alternative ($500-1,000) but may have the same issues.

The S15 Spec-R's 6-speed gearbox is a desirable swap for S13/S14 owners but requires adaptation.

Double-clutching on downshifts extends synchro life considerably.

Other known issues

Common Drivetrain

Clutch Wear and Judder

The clutch slips under hard acceleration (engine revs rise but speed does not increase). Clutch judder (vibration when engaging from a standstill). The bite point moves progressively higher toward the top of the pedal travel.

Common Drivetrain

Differential Wear

Clunking from the rear under acceleration and deceleration. Whining at highway speeds. On LSD-equipped cars, the LSD may lose its locking capability (the car behaves like it has an open diff, only one wheel spins under power).

Critical Engine

Timing Chain Stretch and Guide Wear (SR20DET/SR20DE)

Rattling or clattering from the front of the engine, most pronounced on cold start. The noise may diminish when warm but persist at idle. In severe cases, the engine loses power, runs rough, or misfires.

Common Engine

Turbo Oil Seal Failure (SR20DET)

Blue smoke from the exhaust, particularly on boost or on deceleration (overrun). Oil consumption increases. Oil residue visible in the intercooler piping.

Common Engine

Boost Leaks

Sluggish boost response, reduced power, the car feels slow despite the turbo appearing to spool.

Common Engine

Idle Air Control Valve (IACV) Failure

Erratic idle speed, the RPM hunts up and down between 500 and 1,500 rpm. The engine may stall at traffic lights or when coming to a stop.
