My Yatta Project

[Super Bleeder!!]

The problem with this platform and turbos is torque. The 5spds seem to die pretty quick with auto-X use if they are handling any tq (~250lb/ft)

If i remember right, the 6spds tend to be quite a bit more robust. I can't remember if the mazdaspeed box is even stronger yet.

There are some decent supercharger setups these days that can make 300+whp but no where near the tq, and thus the trans is happy.

It's been awhile since i read about miatas so maybe some of these things have changed.
