In the late 80's Kawasaki produced factory fitted turbo already so it is not a new thing. In the US, you will find turbo charged GXSRs,Ninjas Blades all over, no biggie.
need a little help here... my gsr cam cover cracked so i was thinnking of replacing with a mivec head. is it possible to do up mivec turbo this way considering safety and extensiveness of the total modding package?
