YES! thats what I'm talking about......
I want to know about fitting one to my Z3 3.0i tribute kit also, maybe a Supercharger thread should be started? I saw Lumpy put one on his Z3 2.8i.
Having a quick scan around the web couldn't easily see many for Z3's but did see video on Youtube of chap fitting one to MX5 he bought it 2nd hand off ebay and looked pretty easy to fit.
