Introducing the latest addition of Hybrid bolt-on turbocharger to the 2015+ Subaru WRX. This is a ball bearing upgrade to the factory turbocharger. Tomioka Racing uses genuine ball bearings for the hybrid turbocharger with matched porting to the factory-sized turbocharger housing and TR billet wastegate actuator. The TR Turbo has billet compressor wheel that is 20% larger over factory wheel and wheel-blade that is 17% longer than factory blade. These ensure more surface area for air flow improvement to the turbo. This turbo is perfect for users who look for quick spooling turbo and gain in overall power band. All necessary fittings and gaskets are included in the box to make the installation process painless.
