i need to assemble my 3.63 and no one will do it
 

is it time to buy some dial indicators and do it myself? I can't seem to find anyone who will put it together, so I'm pretty much stuck doing it on my own.

Ship it out to someone that will. That is not something you want to fuck up. Its to easy to ruin it for good by just being off a couple thou. Its small enough as a pumpkin that you should be able to ship it anywhere for a cheap price.

Shove it into a large flat rate usps box, 15 bucks if it comes out under 70lbs.

Talk to sav, i forget where exactly he went but somewhere local to us he got his diff put together.

btw, if you decide to ill send mine out with it if we can get a better deal. I want my backlash checked.

are there any differences what-so-ever with rear end cases? I have a 4.10 torsen pumpkin that I'm trying to swap into and we thought it was a bad R&P so I picked up another 3.63 to try again.

I installed my 3.9 ring and pinion myself and it is still running just fine after several thousand miles. (knock on wood)

The physical iron housings are all the same.

? that makes no sense dude. Are you
swaping the complete 3.6 r&p into the 4.1 pumpkin or trying to get away with swappinng just the ring gear? Or some bastardized setup somewhere in between?

FWIW all of the pumpkins are the same. After you set your pinion depth you check your gear tooth engagement and then set your backlash. After having seen it done, the shit is not that hard so long as you are carefull.

Do it yourself. Rear ends are cake!

You can get a chinese Dial indicator for < 40$ including the magnet base. I've done many a rear end with one.

You can't find a single four-wheeler shop in Texas that will do it?

Rearend Specialists in San Jose, i think.

5 gallon paint bucket = perfect for shipping pumpkins. Even leave the handle on it for carrying.

yeah but those dont measure pinion depth or bearing preload.

Thrash Differential in San Antonio will do it. He did my 3.63 swap. Talk to Charlie Thrash, been doing this shit for longer than you (and maybe I) have been alive. Works with fast cars a lot.

No, I now have 2 Mazdaspeed 3.63 R&P kits.

Are you sure they're the same? People say the 1.8 axles are all the same but I've had a set that did not fit in the hub-splines.

nope, the rednecks won't work on it, if it ain't 'merican made.

tell em its just like doing a ford diff that will ease there minds.

There is a guy on the S2000 forums that builds and sells some really nice diffs. He's offered to help me out with mine several times. I'm sure he would be willing to set yours up. He even builds some "unbreakable" S2000 diffs if you were looking to beef it up a little I would think he could do that as well. His name is Ben, number is 352-650-3763, and his name on S2ki.com is S2KPUDDYDAD, if you want to look for some feedback on some of his work.

I scanned the entire differential section on the FSM if anyone wants it. The only special tools you really need is a bar torque wrench and the dial indicator. The Micrometer is helpful, but I've never used one.

;)

Say car ram rod. Car ram rod. I wrote it down.

Page 41. hello giant micrometer!

Well maybe the miata differential is different than an 8.8 ford, 9" ford, or 12 bolt chevy.. but I've never used giant micrometer to measure that.

I just recently got my ticket last November. Took the test in 94 but couldn't pass the code, then just never got around to taking it again. Working on General now, should get it next tuesday.

Congratulations, I got my novice ticket in 90, upgraded to technician a few months later. I got my general ticket when they dropped the 13 WPM code test. I have not been active in the last five years, but will become active again once I return to the real world.

Stig? Is that you?

Thanks, I'm really enjoying it! Nobody in my family is interested in the hobby so it was completely self motivated. That might be why it took so long to return and take the test. Now that code is no longer required I'm actually interested in learning it.

Too many gears!!!

Call Munzo 469-767-8351. He will swap a miata turbo'ed motor for $480. And that is including swaping all the turbo stuff over.
He has his own shop, and a Super SWEET 450HP 240SX.

He does good work. He put gears in my brothers car.
and swaped rearends and motors for me through the years.

Tell him Todd with the Turbo Miata sent you. He will hook you up. Usually same day or next morning.

ok I'll be honest, I didn't use the 7" mic either. I just put a new crush piece in and used a ghetto-fabbed go-nogo gauge for the preload made of thick sheet metal and ground to to the max and min limits. shit's worked fine for 000's of miles.

hustler: diy baby

:yippee:

I didn't use the micrometer either. I tightened until the bearings felt overly tight and then backed it off a bit. It does make me kinda nervous though.

That may be the single most useful thing I've seen on MT in 2 weeks.

Jesus. Did you forget where the internet was? He's had that shit up for so long I forgot about it. At least I got to laugh twice.

shipping bucket is :bowdown:

I second using Ben from PuddyMod Racing. I just used him to put together my new diff with a Guru LSD. See the thread at 4th pass and "GRUNCH!" - MX-5 Miata Forum for some cool pics of my blown-up Torsen and the rebuilt thing-o-beauty.

+1 on Shipping bucket. I'll have to remember that.


Its not just the picture, the morse code in my signature says exactly what Brain typed out.

Not to be a dick but.... NO DUH

apparently they're getting Steve's dyno too, so I may just do that.

Damn, north of the River FTL (was 4 miles away).
