I do like innovation and I like CR AC (I have 2 setups). I can't get around free heat. I have backdated all 3 of my cars to early style free heat. I do not have a carrera 3.2 so I don't know what's involved to get free heat from that. Weight savings from not using heat exchangers, maybe some. SSI are better than stock. BBE, triad, stock early are all acceptable heat options. If you are running race headers there is probably a version size that has heat exchangers.
