Need technical help! (ex. manifold)
 

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!
