if you're talking about a Renesis, I'd look at this thread:https://www.rx7club.com/forum/showthread.php?s=&threadid=66719 , if you're talking about a 13B REW (twin turbo engine) it is possible and it has been done, someone on this forum with a grey FC has done it but I don't know who it is. I know for a fact that the stock twin turbos do not fit and some modifications have to be done so that there is room for them. Happy searching

edit: I forgot the damn link

13B-RE is the twin turbo 13B from the Cosmo. AJC13B has one in his 1st-gen (big single turbo), and MIKE-P-28 is working on his own 1st-gen swap using the stock tiny-twins in non-sequential configuration. We're all amazed that the stock twins fit!

Of course, those are 1st-gens, not FC's.

I'll be putting the twin rotor cosmo motor in my FC. It can be done and is much easier than any other swap to do.

Basically have to drill mounting points into the humps at the bottom of the iron center block.

Where would you be getting your motor? If you call Jeff at Rotary Power he's working on one right now.

AH, so for the OEM intake manifold vs having one fabbed or buying "piping" adapters that still bolt to the restrictive TII intake Manifold.

Will the cosmo intake & TT work with the FC hood?

Agreed a single turbo can even make more power. Thats why you see so many FD guys replacing the twins with a single.

The cosmo 13B-re actually fits better than the 13B-rew. Very little fabricating needs to be done. Plus the secondary ports are WAY bigger than the stock 13BT ports(should be the same size as the -rew)...

...and go big single turbo...it's the way to go...

what kind of single turbo would be a good combo with the 13b-re? lets say your planning on only making around 300-400 hp
