2 12A's in a 3rd gen body?

Does anyone know if it's possible to put two 12A's into a 3rd gen body? I'm also wondering what kind of power you'd expect to get out of this? I know some of you might think it's a waste when you can put a 20B in or something similar, but I'm just trying to think of something different here. Here's the link that gave the original idea:

Check out the USRRC GT3 RX-7 car for sale and see what's listed with it. Thought it sounded very interesting...

Jeff at autotechmotorsports.com is building a custom 23A 4 rotor 3rd gen. Go to the website and check it out. I've seen the motor and the car in person, it's very impressive.

I'm pretty sure that by two 12A's, you're getting a spare engine - not both installed at the same time.

Thats messed up. Wouldn't a 20B is a better choice? More power plus less room to start..... 12A's have 100hp a piece. One 20B has 370hp, plus it is turbo ready(lower compression). You would have something different however......

The add means spare engines. I don't think that's a real FD either.

That is a tube frame SCCA car-
They aren't really that fast nor-competive. They used PPort 12a's and 13b's because SCCA outlawed all power-adders some time ago in Solo1-

And yes, the add means it comes with a spare engine, not two installed 12a's.

Ive seen the twin 12A motor on the ground at Autotech, and I agree; Impressive. So, is autotech a good place to take my car to get the motor pulled? Ne recommendations? do it urself? how 'bout their rebuild quality.
