Hi, is your car the 1.4? If so, you can get the inlet manifold and bits from a K12 Micra/E11 Note 1.4. I have had an Impul CR-01 kit fitted to my car last year. I got the kit from a guy who imports Cubes to the UK to sell. He has loads of Cube spares. FIrst Choice Imports, Dan Bell is his name. If you do need a replacement supercharger, they do come up now and then on JAUCE. He got me the full installation instructions, but in Japanese. Luckily, I have a Japanese neighbour who kindly translated the who pamphlet for me into English. The charger gives 35 bhp.
