what are the other differences between the 2.2 and 1.8 euro spec except obviously the capacity? i need a turbo manifold for the 1.8vtec and i was wondering if the 2.2 would fit?

well i dont know what engines youre talking about specifically, but ill say the bolt patterns will be different.

so will a turbo kit for the 2.2 fit the 1.8? what turbo parts will i need different?

what car is this for? and what are the exact engine codes?

without this info, im just shooting in the dark... but ill say the manifold wont fit. other than that, you can always customize the piping to make it fit the curves you need.

engine code is F18B2.
