This is the biggest off the shelf Subaru bolt on turbocharger from GTPumps. Based on a TD06SL2 turbine, this turbo makes big power and big torque right through the rev range that really belies it's size. The TD06SL2 turbine is specifically designed by Mitsubishi for Trust to use in their competition engines. Size wise it fits somewhere between the TD05 8cm and the TD06, but has a very lightweight and fast spooling core - like nothing else out there on the market - and you will only find this core in GTPumps and Trust turbos, and GTPumps are the only manufacturer who have a Subaru bolt on application. GTPumps mate this to the 20G compressor wheel to make an awesome street and track turbo. This turbo supports 440HP
