12A in an FC?
Has anyone done this? Will it just bolt in or do I need custom mounts? Want to have a carb and not efi and a carb 13b sounds like a pain so why not a 12a. Will it work?

Why would you want a smaller engine?
Why would you want an older engine?
Why would you want an inferior fuel system?
Why would a carb'd 12A be any less of a pain the a carb'd 13B?
WHY?!

because its cheaper to do.
could i just take a t2 engine and put a carb on it and run it? probably not I would have to get a custom intake manifold and have the injector ports welded over so theres not just a hole there.
so will it bolt in?

your car would be so slow with a 100 HP 12a. you dont need custom intake manifolds to do a 13b. say you went my route, you need the upper intake manifold that matches the car, and a gsl-se lower intake to bolt up to the 13b. with a TII block i dont know what you'd do. its simple with a 6 port

A 12A will also develop much less torque than the 13B and with a carb setup, will be more finicky than the stock EFI.
God, sometimes I wonder about some people...

No, it will not bolt directly in. You'll have to fab a motor mount as the 12A mounts at the front cover. Due to the location of the FC subframe, a new oil pan is required.
Also, swapping to carb means swapping the fuel pump, pressure regulator, a significant amount of rewiring, conversion to distributer, etc.
All this for a 105 HP engine?

No, but it's not my car we are talking about.... he could put a damn hamster cage in it for all I care.
Instead of bashing him for wanting to try something out, how about some helpful advice.

We ARE offering him helpful advice.
He can stick with his original 13B because it will be cheaper, faster, and run better. Giving him bad advice will be telling him to go ahead with the 12A even though it will cost more, will have less torque/horsepower, and will be a more difficult conversion.

This is NOT a matter of swapping out engine mounts - the 12A is SHORTER, so the dimensions are not the same.
This means even though you line everything up with an oil pan and front cover, it does NOT line-up with the stock FC3S engine mounts on the engine subframe in the engine bay.
This means you need to CUSTOM something.
I am not aware of anyone offerings 12A to FC3S engine mounts, so this needs to be CUSTOM made.
CUSTOM MADE usually means EXPENSIVE.
Engine swaps - V8's, SR20, Supra, etc. - are usually about putting something that produces AS MUCH or MORE power than the stock engine that is in there now.
A 12A does NOT make more power over a 13B with similar porting.
So, it is NOT about not being helpful.
It's about trying to prevent the original owner from making a very costly mistake.
If you are really stubborn about doing this, then by all means go for it.

I don't get why you would want a smaller, less powerful engine that will cost much more to install. First of all EFI is better, or maybe i should sayt more accurate not sure how to say it without pissing someone off, than carb thus the reason EFI is used now instead of carbs, But if for some reason you like many other people want to ditch the EFI to go with a carb then it would not be that hard but you would not use the turboii motor you would use either an older 4 port 13b or a 6 port that already came in the second gen, a custom manifold would not be needed since there are companies that make ones that would bolt right up.

I doubt he gives 2 ***** what you think about his concept. Nor do I.
The only irony here is you thinking you are helping him. Get a clue.
Comprende?
