Here is my 2 cents on this.

If you are able to tackle a 20b swap in any of the Gen's then you should have the know how to make custom fabwork. There is going to be alot of custom work involved in this swap.

Ditto.
I dont mean to be a dick,but......If you have to ask,dont ask.

The 20B is NOT a TII swap with an extra rotor attached.Its a strictly Japanese engine that was never brought to the states.It was never sold with a manual trans,and all the literature for it is in Japanese.
There are mounting kits made for a 20B into an FC or FD chassis.....but even with that,there are only probably a couple hundred 20B powered RX-7s in the whole country and only a few that utilize the stock ECU and turbos.Even fewer are in 1st gens,simply because its a brutal torquey engine,better suited to the stiffer 2nd and 3rd gen chassis.

You may already know all this,and if you do,Im sorry to waste your time.But like I said,if you have to ask if theres a "kit"....then you havent given this endevour the serious research that it warrants....

expect to pay 20-30k to get it done. If I pull off the 20b swap I'm looking at, it'll be 20k w/o upgraded drivetrain and w/o fab work. like it was said earlier, if you gotta ask, then don't bother
