that manifold wont bolt up to your head. an std manifold is off of an 88-91 civic standard (std) you can also use the manifold from the 88-91 crx hf or a civic cx (again 88-91). you will have to make an adapter plate to bolt the turbo to the manifold but its a lot cheaper than getting a quality aftermarket manifold. Heres the adapter plates and how to make them. And heres the homepage of that site.
