FC vs FD ex. manifold replacement
Hi guys!
I live in Moscow/Russia. I bought JC cosmo some months ago with 13b-re rotary engine. Now try to rebiuld it. And also I hope upgrade lifeless small hitachi TT to OEM turbocharger. Like garrett gt30r or turbonetic 60-1 ball bearing.
I found OEM exaust manifold on ebay
like this FD3S
or like that FC3S
The qustion is: can I fit FD3S manifold easy to my 13b-re or I forced use FC3S II-gen manifold?
Thank you for help!

Whoa cool, russia huh? welcome to the forum. Besides the point that your english is really hard to understand, I think I do understand what your asking 
The FD3S uses a twinturbo setup, when you say OEM your refering to a factory exhaust manifold? Again its a twinturbo and it won't be of much use to you. I've been told that FD manifolds do not fit, im not sure why but its either the bolt pattern, or the fact that they stick out to much and hit the frame?
If your looking for a decent exhaust manifold, try the HKS log style, I've seen it on ebay a few times for around 300$. You can buy it new, for I believe, the 400$ mark from
www.rx7store.net
So other than that, nice to meet you, and remember, please search before you post. Its not healthy for the forums if something is posted more than once. Chances are, if its been thought of, its been posted. If after searching you don't find ****, then post it!
thx bro

Thanx for answers!
I forgot to insert www link with ebay's offer with manifolds in my post , sorry. And I'm sorry for my bad english.
13b-re is not 13b-rew, and not 13bTurbo. It is hybrid! Some parts are FC and some are simulate FD. Only TT control system became FD.
Thank U for answers!
I will use search engine before asking

the 13b re is not a hybrid,
Its designed similar to the FD motor, But not with Hp in mnd as much as torque.
The housings have some restriction ( designed for more torque than HP ).
If your thinking of replacing the 13b re turbos with the FD turbos there isnt much difference as the 13b RE turbos are a HT -10 and a HT12 ( correct me if wrong anyone ) and the FD turbos are 2x ht 12. They both run sequentially.
so if you want cheap hp, just bring up the boost to 12-14psi . ( 300hp probably cant state reallyy )
If your thinking of getting a single turbo setup and your asking what aftermarket exhasut manilfold to use, probably the HKs log style will for sure fit and wont cost a fortune.
But once you get into single turbo you need aftermarket ecu and fuel mods etc ( all this is already covered here so just search away )

I told about single turbo setup
I told about single turbo setup. I try to find exaust manifold that will easy fitted instead of stock 13b-re manifold. There are 2 types of aftermarket manifolds: 13b-T or 13b-REW. What I can fit?
About hybrid: electrical schemes (like metering oil pump wiring) mostly simular as FC3S. Rotors, exentric shaft, etc. are FC3S.

Just to let you know if the manifolds you are looking at are from a place on Ebay called SSAutochrome.com or XSPower.com do not buy them. They will crack. You are better off getting a HKS manifold and saving youself some trouble down the road
