20b FB Project
Hey everyone, I thought I would let everyone know if they don't already.
I finally have a garage! Woohoo! *little dance*
In any case it's a two car garage with lots of room. I moved my '83 GSL and the '85 GSL-SE in it over the weekend.
This is what is done so far to the '85 GSL-SE (7 hours of work with my friends help).
- removal of accessories from engine
- exhaust is removed
- tubing and wiring are removed
The engine bay is stripped of everything but the engine and steering column. Next we are going to take the suspension off, and then tackle the interior. I will post all the stuff that I will sell once I get a few things organized. Most of the stuff is in MINT condition.
I have tons of pictures that I will be posting and if time permits it, I will be setting up a web cam in the garage so people can watch me be a dumbass trying to fit a 20b into a FB.
Now here is what I need to from you(the forum members). What, if any suggestions or questions do you have about putting a 20b into a FB. (Please don't tell mem not to do it. I've already made up my mind on doing it.) If you have links of other doing it, or other resources that would be great. Hitman's site is okay but he has a modded 13b not a 20b.

I don't want to kill myself in this thing.

Do you already have the 20B?
How much HP are you trying to put down?
Sorry, it just seems like way too much overkill for an FB.
(although I wouldn't mind). You could easily get 500 hp from a properly done Turbo 13B. Check out Rice Racing's FB. this isn't the right link, but it's his as well.

AJC13B (Steve) puts down as much, if not slightly more. I am sure he can tell you it's a handfull, and not cheap either.

riffraff - Yes, it would but I want the engine to last for a while. 
Plus, I would like to keep my ear drums in one peice.
Directfreak - no not yet, but i should have on very shortly. i want to keep the hp around 250-450. (I want to be able to drive the thing around.) thanks for the link! overkill? i laugh at the face of overkill. you should see some of my computers.
Felix Wankel - actually it look fairly easy.

I don't think anyone can argue that they rather have the extra cubes of a 20b. If you are scared of the extra power, you shouldn't be driving a Rx-7. More torque to the ground in stock form then a 13b equivalant. Engine sounds very cool. Envy from other 1st gen owners that get to see it in person. Actually all generation '7 owners should be envious of the power to weight ratio of a fully mod'd 20b in a 1st gen chassis compared to a mod'd 13b equivalant. You won't get any arguments from me how or why one shouldn't do this if they can and want to.

LOL j/kyeah thanks for your support WackyRotary and i agree if someone is scared of a "little" extra power, then they should drive the oscar meyer weiner mobile.
the driving force behind this project, is the fact that everyone seems to be wanting to do a 13b (turbo or na) swap. i like being different and it's a huge challenge too.
I love problem solving issues.

Hey, Trust me, I'd LOVE to see it done. Eventually I want a 20B Turbo in a 91 Vert for myself.
But one project at a time...
Have you considered what ECU you're going to run yet?
As I understand the E6K will not run the 3 rotor. I think Electromotive is the only one that could run it straight from the box, but it is VERY Expensive.
I don't know about the Unicorn, ah... E11 in the works.
Just keep it in mind. In PR they use a modified dirtributor with Haltech F9's to run some of the 20B drag cars as well. That's just another thought for ya.
Good Luck, and post the details of what you're going to use for the whole project. Engine, Turbo, Tranny, Ignition, etc.
I must admit, I am curious, and would love to see it done.

Let us know how you figure that one out. Inquiring minds want to know.

All I got to say is good luck! I have seen a number of people trying this and there is a SHITLOAD of stuff that has to be fabbed anyone see that yellow FB with a 20B, they cut a shitload out of the firewall to do it!!
Good luck man and I'll try to help with anything I know...
But one thing is for sure you better have about 10-12k after you buy the motor! I hear a Motec or something like that will control a 20b's igntion. I hear the new Haltech Ek11 will to? But good luck finding coil packs for them they are VERY EXPENSIVE, id say ask Evil Aviator via PM he knows a SHITLOAD ABOUT 20b's

There is more than enough room in the engine bay without cutting the firewall. Oh, and someone find that yellow FB with the 20b I wanna see it.

Sweet project. 
I've been brewing similar thoughts myself except I'd leave it n/a and bridge or peripheral port it for an easy 300rwhp.
I believe the engine will fit without cutting the firewall but you need to move the radiator, intercooler and oil cooler/s to the very front of the engine bay.
And on the subject of ECU's... I believe the Microtech MTX-12 will run the 20B as it has 12 ignition/injector drivers and they usually sell it as a kit to suit a specific engine so it comes with the correct wiring loom and sensors etc.
If you need some advice on this try talking to some of the Aussie shops as most of them have experience with this sort of swap.

It had some funny graphics on it. But I dont see why you couldnt do it. I think the reason they cut the firewall is cause the used the stock crossmember, wonder how they got a tranny to go in there? if they just pushed the motor back 1 1/2 inches?

If I want 500hp I'll stick with the 12a thank you! And if I want to blow the socks off of a Veyron or most Ferraris with V12s I'll have the 20b!! Only when i blow my 12a up though.
