I'm only going to reply to 18psi because our comrade has not hit me back yet.

Well, that is the point of having so much power.

I thought this was the only reason why people build turbo miatas.


And this guy gets an ansewr because of his excellent username.

A T56 transmission can hold 100% of the hp that it can hold.

talking to Fae via text is like conversating with the twilight zone: a response can be expected within 2 minutes or 2 months.

In for a potential solution.
mostly just 4th gear. But also had a thrust bering issue in one and a broken second gear in another. ~310 -330 ft-lbs to the dyno.

TnTuba. There's still a 5 speed with qualife in the car.

There was a 4 speed for sale for a while. One of those windshieldless cars.

I'm a little late to this thread, but I may be able to contribute:

Other than some gear whine on the highway, they are fantastic gears on a high-powered Miata - the ratios are great and shift effort is like stock. Just about ideal, until they break. While mine lasted for years of abuse at 350+ rwhp on the street and while autocrossing, I've broken two gears on two different gearsets in two summers since I've started tracking the car.

Correct. While you can't find any literature or specs from Quaife stating just how much torque their gears would hold, they were sold to FM as the solution for built turbo cars. When they started to break, Quaife immediately back-pedaled and suddenly they "weren't designed for any more than stock power levels".

And there was a huge argument over what ratios were best/good enough/bad for turbo/supercharged/etc miatas. Is this a factor in transmission availability- ie, everyone who is willing to pay the money for a stronger transmission wants it to be perfect in every way and also wants their own special snowflake gear ratios.

Gearbox options/experiences is a long thread but worth reading. In this post I pointed out a JEGS gearset that just about replicated the Quaife ratios, complete with a more desirable highway ratio. It piqued Andrew's interest and pretty much negated the 'poor gearing' issue for the T5.

I dunno. With the wider Quaife ratios, I would get some wheelspin at torque peak in first, but would pretty much be fully hooked up in second and beyond. This on 205-section street tires (tire width means little for straight-line traction in any case). Stock gearing seems to make it very hard to get traction.

So - at some point the answer is no longer Miata.
While I agree that new weaknesses will be discovered at the mid-400s on, the transmission seems to be the current driveline fuse. I did blow up my Torsen at the drag strip about 6-7 years ago, but that was with plenty of wheel hop. The Guru diff I currently have appears to be bulletproof. No issues with axles either.

After solving inadequate engine and brake cooling issues, the transmission is the final frontier. If an off-the-shelf solution presents itself, I'd happily pony up and start tracking the Miata again. In the meantime, I have a GT4 for my track jollies.

I upgraded my diff to a guru about 10 years ago. Been waiting for a transmission option since then. Been rereading that transmission thread.

[m night shayamalan]It's a thread about transmission options, but it doesn't end with any options. What a twist! [/m night shayamalan]

Yeah with the queef it's quite a different experience.
I had to re-adjust my brain to the awesomeness of 45mph 1st, 65mph 2nd and so on. Really cool on a turbo miata

Add me to the list of those interested. If this becomes a thing I'd be tempted to aim for a bit more power.

Just a little more info. I picked up a 95 t5 for my v8 swapped ranger, and the input shaft is longer.
So if this thing ever becomes a reality, it will need to be tailored to a specific range of years. It appears that 88-93 and 94-95 with swapped input shaft is probably ideal.
I have no idea where the shifter would end up, but note that an S10 tail housing will also bolt up and move the shifter several inches forward. Said tailhousing comes in mechanical and electronic speedo flavors.

Above post gave me an interesting idea for flavored speedos.

They came with an electric speedo for several years as well. My '97 3.8L Mustang box has one.

The parts to swap a later 7.80" input shaft to the early 7.18" length are around $130. You have to be careful about exactly what box you buy (only boxes with a 3.35:1 1st gear can be swapped, IIRC) but it's cheap and easy to do.

The shifter sits too far forward, so the S10 tailhousing would be a disaster. Nothing OTS fits.

What sav says. s10 housing moves it forward a bunch.

Monk, any more t5s around?
