If your not sure what your doing then you better had do a lot of research. Bogg bros can make any manifold you want but if you have the skills then make it yourself. Cbr 600 cars run great on both the cg10and cg13 engines but you'll have to jet them accordingly. Unsure on the ignition side of things but you can get away with micra dizzy etc and ignore the fuel injection wiring. Any questions ask but I'm sure other people have done it too. L
