On your turbo where the exhaust gases go in, is it one big hole or 2 smaller holes? If its one big hole that's an undivided housing and you'd want an undivided manifold for it. If it looks like one big hole but it's divided in the middle into 2 separate holes, thats a divided housing and you'd want a divided manifold.

I'll locate a few pics and come back.

Either way, HKS sells manifolds and I think you can pick those up on the rx7store here... OBX makes decent divided manifolds, but you may have some minor fitment issues on an FC and end up using spacers, etc. Thunderfabrications.com sells custom ones I believe. There are a few around...

Here's a link to an ebay auction for a divided turbo...

If that were an undivided, you wouldn't see the 2 oblong holes on the turbo -- you'd see one big one. (bottom right side of this picture)

that first pic looks like it would mount to a s5 exhaust manifold.....that's what I have. turbonetics said my s5 turbo has cracks around where the shaft comes into the exhaust side of the housing,and they recommended I get a new or used one, or upgrade to a t04b turbo which is really expensive, and is money I don't really have to spend.

I would expect to spend 2-3k on the full to4b setup. I would just find another used S5 turbo if you have the s5 manifold.

and that doesn't include the fact that you would need more fuel and a FMIC as well...

why do they have divided and undivided turbos? does a divided turbo have a 'collecter' in the triditional sence or does each exhuast port go indpendently to each side of the division? or is it for waste gate purposes?

rx7-rage: Do you have a pic of the manifold?

How much do you want for it?
