1.5 (5.5/5.9)
1.2 (20% drop)
1.0 (~17% drop)
.85 (15% drop)
If those ratios come in the form of a 5-speed with a short 1st, or a 6-speed with two useless ratios above and/or below, or even in the form of a T101A with the 0.85:1 ratio in the "1st" position, that's all fine with me.

Using 3.636/3.909s depending on power (3.909s up to ~350whp, 3.636s above that), something along the lines of:
1.5 (5.5/5.9)
1.2 (20% drop)

.85 (15% drop)

You could also have the T101A with a gear venders overdrive to get the final gear on there. It would also give you a gear between gears that you can clutchless no-lift shift to if you only needed a bit more speed in a certain section. I havent been able to get an actual weight out of gear venders but it looks like its in the 20 pound range.

That is good to know now... I bought an MSM tranny with a 3rd gear grind. I've got it torn down and have a 3rd gear, synchro and 3-4 hub sleeve on order. I had a hell of a time getting the 6th hub off and actually destroyed my HB puller. Ended up buying a Snap-on puller off of the truck to get it off. I have a feeling it will be a bear to get back on too. My parts should come in tomorrow, I'll let you know if I come up with a way to get it to go on. I have a 6ft name brand 20 ton press so I shouldn't have trouble getting the whole tranny in the press.

I made my own puller welding a big nut to a piece of plate and drilling three holes in it but yea that thing fits tight. no issues using a 20 ton press to press it on used an oak 4X4 to support the other end of the shaft. got it all together and it seems to shift good on the bench. hopefully I got everything right.

So, while you are disassembling everything, would you be willing to measure out the synchros?
There has been speculation that the s2000 carbon fiber synchro rings might be a drop in replacement. Which might lead to an even better 6 speed, (at least in shift feel and quality).

Gear speed makes better than oem synchros

I dont know fro sure but I have broken seven of the 5-speeds and three of the 6-speeds.
In the five speeds ive broken second gear, third gear, and the primary gears. also had rapid failures like after two weekends.
the six speed I have broken 4th gear twice and screwed up a bearing on the secondary shaft once which might have been caused by a thrust washer for 4th gear breaking off the teeth on the reverse gear teeth on the secondary shaft.
I have never had any issues with Sycro's. don't even see any wear on them.
