Ok, here it goes. I have a 99 civic EX 5spd with the d16y8 in it. Now the question is, will a b16a1 bolt right up my chassis without buying Hasport mounts? The reason i ask, is because the EM1 has the same chassis as mine, but has a b16 from the factory in it. So that should mean it will bolt right up to chassis, correct? Now my next question, all d series motors can be interchanged into other cars that have d series in them as well without mounts, correct? My friend has a EF with a d series in it, but wants to drop a b16 in it. But if all d series can be interchanged without mounts, wont that mean that the b16 will go right in without mounts just like my car? Need some imput.

 

one the is the b161 will have a cable tranny compared to your hydro tranny

 

You will need b-series mounts to swap in a b16, you can't use d-mounts.
