Large Thrust Bearing Upgrade
In 1993 upon the release of the third generation RX7, there were several changes made to the strength and quality of the 13B engine. One of the modifications released at this time was the use of a larger thrust assembly. All three plates themselves along with both thrust bearings were a larger diameter and is a more durable assembly. This assembly also uses a beefier thrust spacer which is also more durable and resistant to brushing when the front main bolt is torqued.
Although these parts can be easily obtained through your local Mazda dealer, REC has packaged these parts as a kit. In order for this kit to be used, you will require a front stationary gear with the large diameter recess or counter bore. This gear is found in 1989 and later engines. The gear can also be purchased through us directly.
