Uno sguardo approfondito al sei cilindri in linea BMW S38: varianti, affidabilità e messa a punto

The S38 variants include the S38B35 (3.5L, 256 hp export/286 PS Euro), S38B36, and S38B38 (3.8L with increased torque). These evolved from the M88 engine for E28 M5 and E34 models.

The S38 is reliable with proper maintenance, thanks to its robust inline-six design and manual assembly. However, mechanical valve clearances require regular adjustments to avoid issues.

Common faults include valve clearance neglect leading to noise or failure, throttle body wear affecting response, and catalytic converter issues in export models. Regular servicing prevents most problems.

Tuning options include individual throttle body upgrades, ECU remaps, and exhaust modifications to boost power beyond 300 hp. Start with maintenance to ensure reliability before aggressive tunes.
