I've seen a CB1000R with a rear turbo in a bike mag. The guy used the original downpipes and mounted the turbo at the rear to keep it pretty. I googled it and came up with a pic. Just a thought mate. It's bloody neat and, from what I read, hauls **** too with not much lag and a smooth power delivery.
