Lots of kitcars have Fireblades in them. If I want to upgrade to a Hayabusa howmuch would it cost? Howmuch work is involved? Let's say the engine is 2000 pounds. What else would I need to put it in a Fury?

Probably another £1500 for a dry sump

poss dry sump as said or a baffle plate as a minimum, exhaust manifold,wiring loom,engine cradle,prop adaptor,gear linkage mods,maybe fuel system upgrades esp if going from carb engine blade to FI busa.
i would guess anywere between 800 and 2500 plus the engine depending on the mods or extras you need.
