can you fit a civic dual carb manifold to a b16a2?
 

i am building a track car and i was wanting to use vtec power although our class rules stated that no fuel injection systems are to be used and carburettors and manifolds must be of same manufacturer as the engine, i know these manifolds can fit the d16 but i was wanting to know if they would fit a b16a2 before i go and fork out for an engine i cant use, also mdoes anyone know anything about civic gearbox ratios
