First of all I expect some respect here for me and my fellow forum members from everybody. So RETed about that dumb *** comment, you should measure your words. My car runs constant 12:6's on an auto tranny and a 6-port TURBO engine. How fast is yours? The drag car did 8:32 with "tire shake" so I believe that I have earned the ****** ******* right to say what works and what does not work. I have not said that he should get a G-Force. I just talked about the benefits of auto trannys, I have also said that I like manual trannys BUT if your car came with an auto tranny there is a lot that can be done with it. If someone asks how long an auto tranny will last I will always say that it will last LONG. Remember we are talking about 1986 and up cars. How many clutch disks and pressure plates do you have to change on a manual from 86 up to 2002 (Quite a few) Most of the auto trannys have never been opened since they left the factory so please get your facts straight. If you buy a used piece of **** don't expect it to smell good.

I don't know about you guys, but I'd rather do 14s with my 5speed and actually feel like i'm doing something than rather just pushing a pedal to the floor and getting 9s. But thats just my opinion, I could be wrong.

I like the fun of the manual tranny, when our drag car had a 3rd gen manual trannny I used to run 9:7's in it. So I know all about it. BUT the topic is about how good auto tranny's are...

I'm with Ted on this one actually.
A stick car will be just as fast as a auto car with a good driver.
Auto trannies have more consistant launches and more consistant times is all.
The auto trannies on stock mazda's suck. That is simple.
A rotary is not a torquey engine, we all know that. Thus is the reason for the rediculously high rpm's required for a good launch. I honestly doubt that switching to an auto tranny behind a rotary engine will be that more consistant. Just learn how to launch the car, use some track data logging, and why bother going through the **** of trying to swap in a domestic auto? The main problem with these cars is not that they don't launch, its just that people don't know how to get them to.
(Angel Guard is now gonna jump on me about how much I know about drag racing them, lol.)

If you're just talking bracket racing, well a sequential is best, but there you go. My problem with autos is, when they run OK the shift slow, and when they shift fast they break (sometimes they break the rest of the drivetrain instead). Racing is expensive, though.
Isn't Soul Assassin running a sequential?

More proof of why I dislike the choice of a C4 for an auto tranny. They will break when they shift fast.
Know how the gear changes in those things work? In a C4, the change from first to second results in an almost immediate change in direction of when of the gear sets. This equals SNAP with a fast tranny.
Look at all they need to do to bring a C4 up to par. Hardened input shafts, planetary gears sets...
do yourself a favour and start with a TH tranny or a 'glide.

Mazfix?, All their cars are 20B, they brag about a full body car in the 7:9's with a 20B engine? Shame on them... Check this out.
We are running 8:32 on a full body (100%metal) 1980 RX-7 with a 2 ROTOR single turbo 13B NO NITROUS.
Our friend Siguel Racing who is running 7:33 on a 20B and still testing, right now he is the world's fastest 3 rotor by the way NO NITROUS. Siguel is also from Puerto Rico, he made 186MPH a few weeks ago, that is another record.

For the record, my car did a 13.447 @ 105.00.  Stock trans...stock turbo.

Before you go spewing all your bullshit, remember, you're on a tiny ****** island in the middle of an ocean.  You're ranting on a board that is read ALL OVER THE WORLD.  If you can't get your mind out of your *** that there's a WHOLE LARGER PICTURE than your island, you're just spreading doodoo all over yourself.

Here's what we can all agree on.
In the original post, the forum member asked how strong the auto tranny would be for drag racing. We all agreed that the US version sucks big time and would not last.
We also agreed that the stock tranny from a J-spec car was not the most suited for drag racing, and would need much re-vamping.
With what is offered in stock cars, the best option would be to stick with a a TII standard 5 spd.
It is possible to swap in a aftermarket tranny from another car, but much work would have to be done.
On the same lines, were you going to swap in a 9" ford rear axle?
Were you planning on switching to a full tube chassis, with lexan windows and fiberglass body panels?
Were you going to swap out the rotoary and use a big block Chevy 632 cubic inch engine?
All of these would help strip performance, sure, but what do you end up doing? Racing a Mazda, or racing the combination of all the best parts made by all the best companies combined?
I'll keep my street/strip car a Mazda with a Mazda stick tranny, and run just as fast as your hybrid auto car with the same mods otherwise.
Topic closed in my mind, original question has been answered.

I can say my car runs 4's at the strip, but its useless if you can't "put up".

so....if i have an 88 auto tranny non turbo...that transmission is crap? is there anything i can do about that? like rip the flywheel back off of a manual tranny rex in a junkyard or what...im gonna be sad if this thing fries itself.
