Looking for a Main Bearing Part #
On the left is the stock rear stationary gear bearing, on the right is the one Mazdaspeed sent me. I am very weary of using it, my stock one used a set screw and has a series of holes in it, I want to say 5-6 holes.
The Mazdaspeed one has 3 long slots and is better for engines living at or over 8K RPM.
Anyone know the stock part # for this bearing on a 1993 engine.
On a side note I am in a "discussion" with my mechanic over this, after reading the Mazdaspeed info on the bearing I feel we should use it he wants to use the stock OEM one feeling the Mazdaspeed one is old school and the OEM one will be better.
Opinions are welcome here.
Thanks
Jim
