an FD engine into an FC is really not worth the work. Here is your answer straight from this Link: http://www.rx7club.com/showthread.php?p=5131155#post5131155

Will a 3rd Gen RX-7 (FD) twin turbo engine (13B-REW) fit in my 2nd gen RX-7?

The simple answer is No! The motor mounts are in different locations as well as other issues; however if you have enough time and money it can be done. Much of the project will be custom fabricating all the systems that attach to the engine such as the exhaust, intercooler setup, cooling system and wiring. A standalone EMS is almost required and it is very difficult to control the sequential turbos. Most people go to a single turbo because of this. In general this swap is not worth the time and trouble unless you plan on making more then 450 HP.

Again, from a rotary guy that has built his FC for track/drift stuff, this swap is not worth it bud. :D
