Isn't that the same Ford 4-speed that was used in the early Fox-body Mustangs?

Be aware, none of the follow up information is correct following the original post in this thread. you are being trolled.

Yes.

Nobody drives a manual anymore. It's best to swap a 2 speed powerglide.

Dude, even noobs have a right to solid info. Just because you don't like people helping this guy out doesn't mean you should discredit all this good info.

Dude...Have Fun With This...

OP, the reason you are getting info all over the map is that is sort of an apples-to-cantaloupe question.

How much boost a 5 can take is going to depend on a few things, some of which are listed below:

Your clutch line. Get braided stainless or its pretty compromised.
Roll bar style. Think about how the bar stiffens the chassis. That stiffer chassis in turn provides more stability for the transmission case through the PPF and the mount. 95's have a bit of an advantage with their stock brace just behind the seats. Style bars help minimally here, but a true roll bar from Hard Dog etc. is the way to go.
Steering rack. A powered rack puts more torsional stress on the chassis, and that can weaken the system. People run a depowered rack for a reason.

More accurately, apples to eggplants.

Answer me this: A sophomore shows up on the first day of tenth grade and asks with a straight face: "How do you dial 911?"

How do you react?

Don't take it too hard, we've all been in your spot at one time or another. Just remember that respect gets respect, and a quick search might help take away the pain next time lol.

The true irony is that not a single post in this thread actually gives the correct answer to your question...

bbundy 05-06-2014 11:18 AM

It must be true, I read it on the Internet.

I will say threads like this are why search dosn't work either.

Are you also new to the internet or the concept of research?

Actually you do have a point here. Searching for stuff using the function on this site basically returns a bunch of cat pictures and threads like this.

Just once I want to see someone build a car using info from threads like this with no double checking or filtering of any kind. It would probably have doors that open downward, use an MP62 as a muffler, run a gear vendors overdrive behind an auto, nitrous directly into the valve cover, plasti-dipped cams, 1.6L, ford 9 rear, and a style bar for a bumper.

However, it took me 30 seconds on Google to find the info required here. It was on Miata.net. :rofl:

I would contribute $50 to this build.

90-93 5MTs are generally luck of the draw - some go at around 150hp, others have been documented to 475hp for hundreds of track hours.

Starting in 94 and going through the 97MY in North America (98MY everywhere else), they pretty much all became butter. 175hp is generally the limit, some have gone to 200hp. There are no documented '94-'97 transmissions running over 215hp long enough to get a good dyno pull in.

To fix this problem, mazda re-looked the 5 speed, but since they ran out of time for the '98 model year, they adapted the old RX7 trans to the Miata in North America for only the '98 cars. Those RX7 transmissions are beasts - there are only 2 documented cases of the '98 RX7 trans going in the Miata, both well over 650AWHP.

Starting in '99, Mazda had generally fixed the problem, and all of the 5 speeds from 99 through end of production are generally expected to hold 450-500 HP for the life of the car. The '99 and on transmissions use different mounting points, though, and are not compatible with any previous Miatas without also replacing the entire front subframe and using the shorter PPF.


Whoa whoa whoa. I did not know this!

I have a 99' but it was built in April of 98. Any Chance that I got the RX7 Tranny? :D

Needs to get rebuilt anyways. It has locked into reverse 3 times already and it getting pretty hard to shift sometimes...

Note to all Noobs who missed it when a couple other people already said it:

ALL OF THE INFO IN THIS THREAD IS FALSE.
