20B trans mission ?
 

ok i have a 1989 vert 13b n/a auto now i have done rims tint sterio and cleaned up the body so i am finlly looking for POWER i need prices on doing a rebuild and turbo setup on my engine and i WANT to keep auto so from my understanding the 20B has a auto tranny most of the time when its shiped over would this transmission hold up better to the hp than the origonal and if so i need a price or some tips on puting it in any help would be appreciated

thanks guys

why do you want to stay automatic?

down with auto...

B/c he wants to get road head, DUHHH.

see he knows whats up no basicly i dont want to do all the work to convert it and its a cruising car c'mon its a vert so im really going luxry not pure racing

I know how you feel man my FE is AT. Most of the time I curse it but sometimes im just damn lazy and enjoy it. It realy is not all that hard to convert a car you need a pedal assembly a hole saw a drill and some interior pices. But since you want to keep it AT more power to you. I have no clue on the durabilty of one. I can only asume it is stronger. I would gues you will spend around 200$ for one and shiping.

In the era..

Mazda had 3 types of transmissions.

The 20B has the Turbo 2 transmission, but of the FD age. One is pull, one is push.

The 20B's transmission is not as strong as the Turbo 2's, aka the Turbo 2 transmission is stronger then the FD transmission. Or at least so I've "heard", quite a few times.

Learn to drive stick, or order a T2 Auto tranny.

Please don't post if you don't have any idea what you are talking about.

The Cosmo 20B all came with JATCO automatic transmissions that are specific that that application.
The Cosmo auto trans does NOT fit into an FC3S chassis.

All Turbo II's (US-Spec) came in 5-speed manual transmissions ONLY.
There was no such thing as a US-spec FC3S turbo with automatic transmission that was offered from the Mazda dealer stock.

The FC turbo transmission is BASICALLY THE SAME THING as the FD transmission.
The FD has more / better synchros AND THAT'S IT.
In fact, you can swap gears set if you wanted to between the gear boxes.

Now, back to the original posters queries...
Please check the 20B section on converting your FC to handle the 20B engine.
I think you're way in over your head.
I dunno what you think is a "lot of power", but a 13BT can produce 400hp easily, which is more than enough for most people.

True. But, there were in fact Jspec TII auto trannys. This is what was refered to when it was sugested to order one.... Corksport had a couple last time I checked.

Ted, please stop being such a dick...

Now, wether that tranny will even work with a 20B is probably unknown because no one who does a 20b swap wastes the time or effort to do it when it is better to use a manual.

Doing a 20B swap is a rather large investment, but from what I have heard it is very worth it. Rather than bash you and say that your over your head I will simply point you in the right direction...

He never said he wanted a 20b.

He said he wanted to stay auto and he heard 20b motors came with an auto trans.

He wants to use a 20b auto trans because he thinks it would be stronger than his n/a auto.

I don't think Ted was being a dick. The person he quoted was passing on info that even he wasn't sure was correct. Far to much BS gets passed on around this forum. Even I got confused reading adrock3217 post.

A dick? Don't be such a nancy boy :).

Also Ted said US Spec, not the Japaneese spec with the automatic transmission option. So lay off and leard to read :).

Yes, adrock's post was incorrect, but Ted also blasted the original poster for trying to put in a 20b in when he didn't even say he was going to put one in.
As for the tranny, I would suggest getting an auto from a j-spec car. Since they were all Turbos I'm sure they are stronger. I would contact corksport about it as suggested.

Sheez people. Ted also said a 20b AT tranny does NOT FIT into a FC chassy!

Juiceh - Stop atcing like your going to school TED then post a link to his own web site.

holy mackrel boys....

Perhaps one of the items on tshirt "you know you're a 7 owner when" should be:

You read posts from whiny little fruits who complain about posts from other whiny little fruits who were distressed about a correct post made by a moderator...

RELAX - and Ted right to point out that the guy is in over his head if he's thinking about a 20b swap.....try making similar numbers with a 13b first then think about a 20b swap....

CORRECT he didn't say he is going to but come on - he said he wants to put in a 20B auto tranny...what do you think his next logcial thought is going to be for a mating engine?

GEEEZ sometimes you guys get so technical it makes me wanna get a job at the post office....

Ted is just doing the job of keeping the misinformation out of the 2nd gen section. Trust me, a lot of it goes around here..

i have a current fuel issues thread going and the answers i have got in there make me wish i could delete the replys. its sad.

The 20B autotranny might handle more power, but the required fabrication along with the loss of power using an auto makes it nearly worthless.

It would actually be easier going through the trouble of installing a manual tranny then trying to get the 20B auto to fit.

I suggest you reread everything before posting falsehoods.

From the original poster...
There is NO such thing as a "T2 Auto tranny".
"T2" implies US-Spec, since the FC3S turbo was NEVER called a "Turbo II" or "T2" in Japan...or outside of the US / North America.


You got a problem with me, PM me in private.
Try and keep your personal attacks on me out of the threads, cause it's already bad enough that you're wrong, but now you look like a whiny bitch who's also wrong.

Happy New Year.

ok guys stop your bitching and yes i was giving thought to a 20B conversion but i guess im not going to at all so the NEW question is what can i do to MY tranny to make it handle about 350hp and i know it will not be as fast as a manual but sorry my car my choice again ANY help appreceated
thank guys for the info it did help alot

You need to learn how to drive a 5-speed if you think an NA tranny can be built for that.

I'm guessing it'll be a grand or two if someone had even the parts. Not to mention there are no aftermarket torque converters.

PS: Go Ted. He's just making sure people don't misinform peeps.

if you want a fast automatic, buy a 'Maro with a stall converter

ok guys dont start burning me i DO know how to drive stick but i DONT WANT ONE this is a cruising car not race car so im guessing that that trans will not handle jack s for power ok then hmmm.... how does the auto trans work is it a electronic and if so does it have anyting to do with the engine managment sys????

IMO your best bet may be to fab a FD AT trany in. That trany should hold 350hp at the flywheel. They came with 280 in japan from factory.

thank you blue how much you think one would cost??
