A guy i know has a bj60 3b with a turbo and i went for a ride in it and it goes pretty good even with 37's. He gets about 10psi boost. I want to use the same turbo but the identification tag has worn off and the only numbers i could get were on the face of the compressor housing it is an air research turbo with M27 on one side and GIL2 on the other anyone know what this turbo is from?
