6 speed MS trans
 
Is a MS 6 spd trans worth 1100 shipped?

if you vote, post a bump

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.

cjernigan 09-06-2007 05:17 PM

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.

Loki047 09-06-2007 05:18 PM

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

Ben 09-06-2007 05:27 PM

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.

cjernigan 09-06-2007 05:41 PM

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.

paul 09-06-2007 06:49 PM

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

krayzrac3r 09-06-2007 07:03 PM

paul i just got the 3.9 for my 5 speed also however its not installed yet. Just curious what a couple of your gears do (mph) especially 1st,3rd, and 4th of you dont mind

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.

paul 09-06-2007 08:11 PM

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 ;)

Savington 09-06-2007 08:13 PM

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

Ben 09-06-2007 08:17 PM

fuck 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."

magnamx-5 09-06-2007 08:29 PM

I did it not 1/2 a mile from my house hell. If you have enough hp it comes up pretty quick

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.

haha, awesome. at 52 points on my license I don't need to be hitting 150+ mph on the Garden State Parkway.

plus my girlfriend was in the car...

y8s 09-06-2007 09:12 PM

under 300 rwhp, not worth it.
over 300 rwhp, questionable.

soflarick 09-06-2007 10:12 PM

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.

neogenesis2004 09-06-2007 11:57 PM

I got mine for $650 shipped. My power goals are very ambitious.

Newbsauce 09-07-2007 07:06 AM

I saw the last one on ebay go for like 700, theres no voting option for "That shit is overpriced, wait and get a different 6 speed"
