Full rads are super overkill. Civics are all half rad. If you have a full, not only the manifold issue but also the turbo housing is a big part. Another thing is do you want to keep p/s and a/c?Like Hooligan stated, it depends on the manifold. You can keep the full width radiator with a Revhard or InlinePro style manifold. I have a side mount manifold and I also run a full width radiator. The SLS Shorty will fit with a full rad. Keep in mind you will have to front mount the rad fans with any of these manifolds. But honestly I wouldnt worry about a full rad since many before you have been successful with a half width radiator.
I'm planning to keep both in the long run. I know that the half rads will function just fine, just rolling it around because it will be my daily for a while and like I said, don't know how a half rad would do. Any specific half size superior for the compatibility? Was really looking into Mishimoto since a lot of people have good to say about them.Full rads are super overkill. Civics are all half rad.

A little bit. But really with a half rad you're gaining efficiency and losing surface space. You will be fine with a half.I wouldnt say they are super overkill. That statment is super general.
