Doesn't look that far off from a miata 5 speed but has a longer 5th. (Going from memory here, haven't looked at the ratios in a couple months)

1-3 are also noticeably shorter.

The gearing is fine, unless you want to shave every second possible from your lap times, in which case I assume you already have a custom gearset for every track.

If you are not into track/autox, the TII/FD transmission is fine for up to 450-500whp.

But if you're not into racing the rx7 trannies are too hard to install, they dont bolt in.

The amount of fab work required to make them work is a small trade off considering the added reliability. I'm going TII because I don't want to deal with blown transmissions every few weeks. I also want to be able to still drive my car after it is making real power without fear of my drivetrain exploding at any moment.

The added time of installing one TII transmission is still less than doing a 5 or 6 speed twice

Yeah, but its a street car. You cant put non-bolt on parts on a street car.

Just go with it. It's Leafy being Leafy.


If you NEED a TII/FD trans, chances are you're way faster than he is anyways, so does it matter?

Which car is faster: The 450hp Miata with the TII/FD transmission, or the 450hp Miata with the Miata 6spd?

How fast is the tow truck that is towing the miata with the 6 speed?

On a track the 2nd one will hold the faster individual lap time.

Assuming it can complete a single lap.

Let's put this another way.

Which car is faster on track:

1) 450hp Miata with an FD trans

2) 300hp Miata with a Miata 6spd


Because these two cars would hold together.

Does anyone actually know of a 6-speed being broken in a street car?

Does anyone making power enough to break a 6spd actually notice the "awful" gearing of the FD transmission in a street car?

Soviet would probably break one, but he doesn't drive it because he's paranoid about it after all the horror stories you track guys have posted.


I'm getting confused though... the big argument FOR the 6spd was track performance when it's holding together.

Or are we saying that the superior geared but weak 6spd is better than the stronger FD trans on the street where gearing doesn't matter, and better than the FD on track where strength does matter?



I think the point a couple of us are trying to make is that if you're making too much power for the 6spd, the FD/TII trans is a solution that's available NOW that will hold pretty much any BP on the site, and costs peanuts. Ideal? No. Better and way cheaper than replacing a 6spd 4x a year? To many people.

The last FD tranny I saw costs just as much as all the other options we have that are just as strong as the FD tranny. 2-3 grand.

So get a TII trans. Jesus.

My FD trans cost me $600 and i had my pick of 4. These are not expensive transmissions, stop shopping on ripoff.com: The Leading Ripoff Site on the Net.


HAHAHAHAH, i didn't even click that that was a real site. Whoops.
