How does the B16B EK9's intake manifold compare to the ITR B18C one?
Are they the same part?
Are they the same part?
i dont know about that, i am pretty sure they are the same part.
biggest differences are that you've one resonatorbox less and an different formed air-filter.
Also it's designed for the 1,8l engine... trie it
I dont think the chamber is larger, its the ports in the runners that are larger. The fact of that would be due to the lower intake air from the B16B.
But size of runners/TB need to be matched to engine size/air intake amount to work properly. So by simply putting the larger/higher flowing manifold on the B16B without any tuning is pointless.
They are identical.
Is this for certain mate?
Yup, same casting, may be small differences like mentioned above there is 1 nipple in the rear but as far as plenum volume/port shape/size/runner length/etc.. they are identical.
I would guess Honda just used a smaller TB on the ek9 to make up for the design of the IM being for a 1.8.
um can i ask something? im buying a ukdm itr b18 cylinder head on the weekend and sticking on my b16a2, do i have to buy a b16b/b18 inlet manifold?
Yes, also the OEM IM is plenty for B16
