    Question, Had an idea today, as the ports are different on the carb/injection heads and the inj tb wont fit on a carb inlet, would it be possible to cut n shut a carb & inj inlet and use a 1.3 carb head???

    will the 1.8spi throttlebody and 1.6 manifold work just as good on the 1.2spi as on the 1.4spi because ive got the bit lying around. the enginjes already got a 4branch, c16se cam, and a cotton green air filter.

    cheers damen.

    what is a 418final drive when you say fit it to the f10cr or f13cr box. Also the 1.2i's exhaust mounts are they the same as the sri/gsi's.

    It wont fit as you need the lobe to run the fuel pump on it you need a 1.4 sr cam mate but if you get one its a straight swop.
