I plan on upgrading to GT675RS Turbos from Z1 shocks are old and honestly just figure it is easier to do this work when engine is out...I will retourque everything once new motor is in and tires are on the ground.....I am keeping stock motor other than adding the turbos and a dual pop charger and will upgrade ecu. New Springs will be included along with some shocks....thinking KYB adjustable I will not be drifting just looking to build a FAST streetcar.
