Difference in turbo vs non turbo 6 spd trans?
#26
That's what i get for listen to one source rather than many.
Local Miata "Guru" .. um .. yeah "Guru".. told me that the change was made in 95 after tranny issues started happen when they switched to the 1.8.
This appears to be incorrect info.
I'm going to raise the BS flag with him after work today.. heh..

I just looked up the 6 speed internal parts in MazdaEPC and the answer is yes, the turbo has a different gear set than the non turbo.
Example:
99-05 non turbo 2nd gear is part Y601-17-251, retail $188.55
04-05 turbo 2nd gear is Y611-17-251, retail $191.90
I would interpret this data as the turbo trans has peened gears and the non turbo car does not.
The Torsen LSD in the turbo car is also completely different than the non turbo LSD.
Example:
99-05 non turbo 2nd gear is part Y601-17-251, retail $188.55
04-05 turbo 2nd gear is Y611-17-251, retail $191.90
I would interpret this data as the turbo trans has peened gears and the non turbo car does not.
The Torsen LSD in the turbo car is also completely different than the non turbo LSD.
Question now is, how much stronger are they?

Mark, have you experimented with different tranny fluids to see which one appeared to perform the best? I finished my 6-speed swap, just using generic 75w90 gear oil to put some mileage on it to clean it out, then I was going to run Amsoil 75w90 Severe Gear like I did with the 5-speed. It's nice I don't have to sweat the turret oil fill, and can fill the tranny through the turret instead of spewing the nastiest of stinky lubes all over myself and the driveway.

Wheels are easy to find... Junkyards everywhere have them.

The six speed is always stronger than the stock 5 speed, and by a significant margin. Broken six speeds are rare. Only 1 or 2 broken ones have been reported thus far on the net.

Have any of you had experience with this before? Has anyone heard this sound?
Thanks for the input.
