Perfect, except 5th is a little deep as Bob said.
Read this thread, especially from post ~125 onwards, for a lengthy discussion of what gear ratios are ideal and why they are ideal.

Also for discussion Last night I peced together a gearset in that Richmond 6 speed. It can be made very close to what can be found in the NISMO AZ6 or it can also be made very close to the stock Miata 6 speed with a taller 1st and 2nd. first time I seen anything like that that you can get the gearing right in. cost about $3700 from summit for the box. I think you can buy the bellhousing to fit it to a BP from summit as well.

I think those ratios would work quite nicely for a high power track car.

Which takes us back to needing a 6 speed to have a good auto-x box and a good RR box. Like the Richmond Gear 6 speed with the 1.125 x 26 spline input shaft
2.77, 1.88, (1.67, 1.52, 1.46, or 1.36), 1.19, 1.0, 0.84
This is like a $3900 tranny, dry weight of 108lbs. So its a weight gainer compared to our 6 speed but you'll never have to think about it again. A a bonus, the fitment we want is the C4 vette which also has a pickup for a torque arm that was should be able to make a ppf adapter for.

I'm running it with my 3.90. I'm not a track guy but it's nice on the street. The standard .63 5th is a HUGE drop in rpm. I'm at ~2700rpm at 75mph, which is nice but the .8x 5th is on my to-do list.

T-5z is the world class trans. Technically a 330ft-lb capacity in a heavy mustang doing dragstrip yank the wheels launches with dragradials.
I know of racers running significantly more than 330ftlbs thru them on the strip.
But yeah maybe, apples/oranges application. Maybe the extra heat from road racing will cause damage in similar time to the 6 speed. That would suck.

I keep thinking about BP to T5 adapter.
Here are my thoughts:
- Most common Ford T5 has 17mm tip of input shaft. Miata pilot bearing is 35mm OD. Fastenal has a bearing just that size
- T5 pilot bearing (at least on Ford transmissions) goes into the block while Miata pilot bearing goes into the flywheel. This gives enough offset for an adapter plate that would sit between stock T5 bellhousing and BP block.
Ideally, the adapter plate would sit between miata bellhousing and T5 because it has a simple, easy, 4 bolt flange. But miata transmissions don't have separate housings, the whole front part is one piece.
BUT!
There are also automatic miatas, right?

This is a 90-93 automatic transmission and it appears to have a very nice, separate bellhousing. Now, its an auto so there is no provision for a clutch fork. But thats a much, much simpler problem than not having a bellhousing, imo.

I am also looking into this and have one of the T5 rebuilders commenting yesterday
"I was able to confirm that the Quicktime RM4097 bell housing will bolt
to the 88-92 Camaro T-5 case and would expect to have the Camaro size
input shaft! "
Yes it is $600-700 for the bellhousing and it will be steel, but it is readily available and claims that it does not require further fabrication.
G-force has apparently stopped producing dog ring gear sets for T-5, too many issues with people wearing them out and asking for warranty rebuilds.
Looking for other vendors providing straight cut dog ring gearsets for T-5...

Are you looking for straight cut gears or dog ring? I don't know if g-force ever had a straight cut gear set... they only show helical dog ring and helical synchronized. No straight cut gears...
You can get a faceplated TKO600 from Liberty's Gears. It should also bolt up to the Lakewood housing. They could faceplate any other transmission, e.g. T5 or whatever. New Page 1
As far as I understand, faceplated and dog ring is more or less the same thing.
edit: google shows that g-force did have straight cut gears circa 2008 (?)
