I see the tranny generally going for about $700+/- $100. Figure freight to be $100-150.

Unless your power ambitions are high, get a 5 speed; you'll be happier with the ratios.

The only reason i would want a 6spd is if i was going to swap the 6th gear for a something with a taller ratio. The strength of the 6spd is nice, but do you need it.
If you want a taller ratio, you should swap your ring gear and pinion for something like a 3.6 or w/e people were discussing recently.

I will need the strength and I guess the MS 6 spds are stronger than normal 6spds

I am unaware of any differences in the tranny. The MS does have beefier axles than non MS cars, making the rear swap a little more enticing. Not that I've ever heard of an axle snapping though.

You'll want a 3.6 R&P if you get the 6 speed. 1st is pretty useless, you might be better starting in 2nd.

Starting in 2nd with the 5spd is nice when accelerating quickly. With the stock 4.10 or 4.3s my '99 has. Pretty sure it's 4.10.

I love the gearing with my 5speed trans and 3.90 rear. Can't imagine shortening it with a 6speed trans or 4.10/4.30 rear.

Now 2nd gear gets me just over 60mph

obviously you can't go by what the speedo says because it will show the same speed as it did with the 4.10 rear. i will go out and get some numbers for you on my tomtom.

brb...

My miata is still NA, but in my old GTI turbo, it liked the longer gear ratios so you could stay in the boost longer in each gear. I kind of like the idea of the 5-speed w/ 3.9 - you should be producing plenty of torque so no wories about the 1st-gear launch.

When I was on the Vortex, you should have seen all the whiny posts from the guys with 337's and other special-edition models that had 6-speeds with shorter ratios. Apparently(they said) 5-speeds put up better 0-60 and 0-90 numbers because ratios forced an extra upshift for the 6-speeds.

OK, results from my TomTom which I've determined is pretty accurate once it catches up so that meant trying to keep it right at the rev limit which is pretty tricky.

5 speed 94 trans
3.90 Torsen
215/45/15 tires which are a bit smaller than 205/50/15's

1st- 37mph
2nd- 63mph
3rd- 90mph*
4th- 118mph*

When I get the thing on a dyno I'll post those numbers.

*uhhh, these speeds were reached on a closed course, not a public roadway

Paul, did you have a GPS on that "track event" or were you using the stock speedometer?

**** that 'closed course' bullshit, we're not pussies here

Here, I'll make you feel more comfortable, "I've had my car to rev limit in 5th gear on a public highway on multiple occasions."

Those were the speeds on the GPS. They do mimic the speeds shown on the speedo now that it's more accurate with that rear and tire combo than it was from the factory.

under 300 rwhp, not worth it.

I have a rebuilt 5-speed and 3.90s. Excellent combo for my engine's output. I'd only consider the 6-speed if the engine makes enough that reliability is a concern, but then I'd want a set of 3.63s instead of the 3.90s. With the 3.90s, first gear has a use. Cruising rpms are a bit lower as well. I think the longer one waits to get a 6 speed, the lower the prices may become as more cars with them wind up in the boneyard.
