20b questions

For those of you who don't remember me, I bought an 83 gsl with a seized 12a in it (it was the original engine). After lots of research without actually tearing the engine apart, I found out that it overheated (called the dealership it was last serviced at) and that it died soon after.

At that point in time I picked up an 86 fiero se (no flames please ) and I am fairly happy with that, but I cant get over the idea of running off a rotary engine. Besides, the fiero can be my dd until I get the 7 running again.

Enter roughly $10,000.

Now that I have the money, I'm really interested in trying to get a 20b into my 83 gsl instead of just rebuilding the 12a. I have the feeling someone has had to have done it before, but I don’t have any idea how they would have done it.

How do you mount it (would I have to fab mounts or could I buy them somewhere)?
What do you need to swap for it?
Can I/should I use aftermarket injection so that I dint have to re-wire the whole car?
And most importantly: WHERE DOES ONE GET THEIR HANDS ON A 20B? I honestly have no clue at all. (I know –think- you can make them with two 13b’s, but I wouldn’t know how to do it or where to get the parts for that)

Any and all comments/advice is more than welcome.

As I understand, it's pretty much entirely custom, and very expensive. (If you do it for $10k, lemme know... I'll do that instead of buying an FD )

You may want to poke around the 20B forum on here too

Thanks for the help guys; I will keep you posted as things progress. I will post the remainder of my 20b questions in the 20b forum, but I have a few more general first gen questions:

Does anyone know of any mounting kits for the 20b in a 1st gen? Should I worry about the tranny? Etc.

Just trying to gather some info here

Whew, thought you were gonna ask about putting a 20B in the Fiero.
Actually, the thought did cross my mind. You would be amazed how many kits are out there for engine swaps for that car....

I recall the Fiero and CRX being my 2 favorite cars when I was younger. I ended up buying a CRX eventually...never did get a Fiero.

Mounting Kits?

Nah, nobody makes those - no way to make any money on them. Just ask the last guy who paraded through here about making a kit and becoming the next Iberra
