🔍 Why Choose TMC Motorsport?

All of our turbo kits are built in partnership with Saito Italy, the official authorised European distributor for Mitsubishi and Garrett turbochargers. We only use genuine, performance-proven parts.

⚠️ Don’t be fooled by cheap turbo copies. Many are made in China using poor-quality materials and are prone to early failure. TMC kits are trusted by tuners worldwide for their durability and power delivery.
