I think your best bet will be the TII swap or a for big power, Find a G-force GSR four speed. I have a 2002 6speed and it hasnt broken any teeth yet but my 330ftlbs doesnt come in untill 6800 rpm
I could have sworn you guys (sav) had said that the quaife gear set was rubbish due to sticking it into a shitty 5spd case. PPG used to offer 6spd straight cut dog sets.

If the first was between a 5 speed 2nd and a 6 speed 3rd. Would it really be that bad? You would have to slip clutch/spin tires to launch quickly from a stop and you might want to winch it on the trailer. But from the few times I've spaced out on the street and left the stock miata in 2nd and pulled away from a stop, it wasnt that bad.

It shouldnt matter from a stop light if you're trying to drive the car like a normal human being. Next time you drive a miata just try to accelerate at the same pace as everyone else, but pretend 1st doesnt exist. You rev a couple rpms higher and slip the clutch an extra half a second taking off and the car just feels a little bit slower until you get to 5-10 mph when you'd normally be shifting into 2nd anyways. Without a doubt it will end up reducing the life of the clutch.

A 4-speed T101-based setup would work on a road race car that was winched onto a trailer and was geared for 80-105-135-170mph in 1-2-3-4th. Paddock crawling would be all but impossible, but it would work on track.
This is why I think the 6-speeds and the Quaife boxes have the gearing down pat, and any custom solution should match those ratios within 2mph. The 6-speed gives two crawler gears, the Quaife gives one, but both boxes give 4 usable ratios on track.

Some 6-speeds are better than others. MSM boxes seem to shift the best out of all of them. It takes some getting used to, so just slow down your shifts until you stop missing them and then slowly ramp the speed back up. I don't miss shifts in 6-speeds any more than I do in 5-speeds.

Not sure if anyone has seen this company? I've delt with them for FWD G-series stuff but not anything RWD. The dogleg 5speed definatly has me intrigued, seems like much less misshifts would be possble. But being as 5th is 1:1 not sure its usable... They also have dog and syncro engagments for the 6 speed too
