I was told by a local shop that any b motor throttle body will work on a y8 manifold?Is this true?I have a z6 and tried TB'S from a B20,H23,and ls motors they all have the same diameter opening as my stock z6 TB.I want to go bigger but I don't want to spend 300$ on a racing TB when I can just get something bigger from another engine.
