need to get info on 13b engine
 

hello all.

i have a injection 13b and i need to know how i can see if its a 4 or 6 port if it a first gen or sec gen because a guy want to buy it for a plane and i need a sec gen 13b.

thx for all the info you can give me.

Pull off the lower intake manifold... Are the 6 ports or only 4...?
