Another eBay 6spd $500
 

no affiliation

good deal if the yahoos don't run the price up

man one just ended for 700 bin. I hope these deal come up when I actually am ready to buy.

a credit card will make you ready now ;)

haha, i'd need to get a new one :-o

Too bad it's in Ontario. :-(
I asked the seller for a shipping estimate though. We'll see.

i dont get whats soo special about a 6 speed. All ive heard about them is that you have to shift more than the 5 speed and on the highway your revs are higher. Is there something I'm missing here?

Yeah, they don't break.

How strong is a typical 1.6 5 speed trans? Is it common to break one with 200hp?

not before the rear.

I think the 5 speed will handle what, 270ish before you have to worry about it?

I think a lot of it depends on how you drive and what you're doing. Drag racing will kill it at 250ftlbs, but I've got a buddy who tracked his 300rwhp Miata for five years on the same trans and it's still going.

Ok good. I'm just tired of buying upgrades just to get my car ready for higher boost. The only weak part left on my car is the clutch. I need a clutch and fuel pump and I'm DONE.

Dude....too funny WE'RE NEVER DONE!!!

soooo tempting.

Go for it, you probably won't find one closer.
The seller wants $200 to ship it to me :sadwavey:

already sold or I would have :(

WOW $510, someone got a good deal

*Tears*

found another for 599 in texas though...Dam that was a good deal.

I would have thought the opposite is true. My Miata sits at about 4k rpms at 80mph, twice now I've gone searching for that 6th gear only to remember there wasn't one and it has to go back to fifth. But I guess the 6-speeds could be geared in such a way that 6th isn't much higher than the 5th we have now. Is this true?

6 spd cars came with a 3.9 ratio rear, some crazy overseas models were 3.636. Your 92 has a 4.3 ratio rear. (then 4.1 in the 1.8 NA, and back to 4.3 for the 5 spd NB) You'd want to source a numerically lower gear if you got a 6 speed. It's really not that hard, you can find what you need out of a number of mazda trucks and rx7s. Someone has a cool list of other mazda gears compatible with the 7" miata diff, maybe they'll post it up.

The 6th gear in a 6 spd is shorter than the 5th gear in a standard 5 spd. The 6spd is a stronger transmission and was mated with a 3.9 rearend(correct?). If i was to swap in a 6 spd I would do some research and have a taller 6th gear installed to get some gasmileage and top end out of it other wise the only benefit is strength over the 5 spd.

Yeah, I was planning on getting a higher rear as well. Good to know on the 6speed, thanks for spoon feeding my non-searching lazy ass. :)

Is anyone actually looking for a 4.3 Torsen out of a 5 spd NB? I'd gladly drop to a 3.9 or better yet a 3.63 Torsen for a swap.

Sure, 4.3 would probably be a great gear for track duty. But if I were looking, I would probably go 4.10 with the rx7 5th gear.

here's your 3.9. That's about half the price of a new 3.63 from mazdaspeed. I'd still spend double for the 3.6 though. It may slow the accleration, but not enough to notice (only on the timeslip) and the lowered cruise rpm would be worth it IMO.

better yet, call 915racing.com in TX and I bet you can source a 84-85 GSL 3.909 cheaper.

or try the:

3.700 - 808/72-75 RX-3
3.636 - RWD 626
3.727 - 76+ RX-3
3.308 - 82-84 B2000/Courier Diesel


here these guys: http://cgi.ebay.com/ebaymotors/Mazda...2328QQtcZphoto

just call them, they can get the 3.909

is that where you got the one that you sold to yates?

I'm currently running a 5-speed and 3.636 gears in my 2000. I really like that gearset. If you do the math on the custom FM gears, my first gear w/ the stock 5 speed is very close to their tall 1st gear w/ stock 4.30's. All that to say I like my setup. Now if I can just fix the speedo.....
