6 speed and 3.9 rear end swap
im possibly getting a sweet *** deal on a 6 speed and 3.9 torsen out of an 03!
and my question is will the axles from my car directly bolt up to the 3.9 torsen out of the 03? my car currently has the 4.10 torsen!
is there anything i need to know as far as the swap goes?

I'm referring to the thin metal plate that goes between the engine block and transmission, also has the grounding strap on it. The dipstick also attaches to it.
Can't beat a free swap.

Yep, better to use the 6-speed starter than keep the 5-speed starter due to attachment differences. And it's there for the taking, so might as well.

Almost every (or maybe every) 1.8 diff I've seen die of natural causes was an 03. Many were simply assembled wrong at the factory. I have posted pictures before.
Almost every LSD failure I've seen is a T-F, where the clutch breaks apart.
03 was the only year of the 3.909 T-F. Sounds like fail on top of fail to me.

You'll be fine with swapping everything over, don't worry. The 03 Torsen isn't the best of the OE options, but for what you're doing, you'll never notice the difference. Maybe down the road if you seriously get competitive in autoX or something you'll notice it's performance shortcomings, but until then.....

Threads are hard to find, but if you search hard enough, you will find jems like these:
Differential going? - MX-5 Miata Forum
Something fell out of my LSD diff. What is it? - MX-5 Miata Forum
The common thread between the blown up 03 units is that they all seem to die with low miles on them, so if the particular unit you're looking at is higher mileage, it might be just fine. Kind of like the 97-00 thrust bearing failures; if it didn't pop by 40K, then it's probably not gonna (though some motors did give up the ghost around 100k)
