• 🔥 Turbine replacement — standard T25 changes to Garrett T28 or T3/T4 for more boost.
• ⚡ Intercooler — installation of a front intercooler (for example, from GTS-R) reduces air temperature and increases efficiency.
• 🛢️ Fuel system - replacing injectors with Nismo 370cc or 550cc, installation of a high-performance fuel pump.
• 📊 ECU — chip tuning or installation standalone-systems (for example, Haltech or AEM).

2. Suspension and brakes:

• 🏁 Springs and shock absorbers - popular kits from Tein, Koni or BC Racing.

• 💨 Turbine wear — standard T25 serves about 150–200 thousand km. Signs of malfunction: smoke from the exhaust, loss of power.

2. Transmission:

• 🔧 Synchronizer wear - especially in 2nd and 3rd gears. Solution: replacement with kits from OS Giken.
• 🚗 Leaking gearbox seals - a common problem after 200 thousand km. Solution: replacing oil seals and seals.

3. Suspension and steering:

• 🏁 Wear of silent blocks - especially in the rear suspension. Solution: replacement with polyurethane bushings.
• 🔄 Play in the steering rack - requires adjustment or replacement.

4. Body and interior:
