My last rebuild

new:

Rotor seals/ springs (all)
New Housings
New Irons
New Bearings (Rotors & Gears)

Re-used

Rotors
Shaft

Cost me about 4,000.00 I get a dicount at a local mazda dealer. He priced it at just below mazda trix (and I did not pay shipping to FL).

But to each his own. I dont like pulling motors, some of these guys live for it. I like to get my cars runing and drive for years befor doing a motor job.
