did anyone see the last episode of hot rod garage where they were challenged to build a Barra motor out of australia. so since they couldnt find a inexpensive barra motor and ship it to america. so they went and got a 4.2 L vortec inline 6 and added a single cheap Chinese turbo to it and tuned it. they pulled some badass numbers on that. next season they are doing one with twin turbos.
