I was looking at the mazdarix web site and noticed that they have "competition thrust bearings and competition oil control ring springs.



Do any of you guys know any thing about these parts.? Are the competition parts worth running or am I better of sticking with OEM..?????

Could it be that these parts are OEM Mazda competition parts..?





Thanks again guys.

if you look closly at the part numbers most of the comp parts are mazda parts from mazdamotorsports. and yes they are worth it if you are buildin a spirited to race engine or just want a lil safty barrior when putting an engine together

the oil control springs are beefier to try and keep the rotors off the side housings @9000+rpms



the thrust bearings are just for heavier loads (bigger clutch, more rpms etc), the 93+ setup is prolly better, its got larger bearings



if you're not revving higher than 8500, you prolly dont need this stuff, its for reliability at high rpms. the stock stuff will take 8000-8500, this stuff will take more longer https://www.nopistons.com/forums/pub...#>/biggrin.gif

Also, clearancing the front thrust based on what your intended application is will help in the long run by keeping excess load off of the torrington bearing faces at higher rpm's.

Because at high RPM's the e-shaft starts to flex a bit, And takes up the extra end play. Right?

Yeah I really like the 93-95 trust bearing setup..



But my rotating assembly has already been balanced. And I'm pretty sure to upgrade to the 93-95 you need either the 93-95 front stationary gear or you can get the 2nd gen stationary gear machined to fit the larger thrust bearing. Plus I think you need the 93-95 thrust washer, thrust plate, counterweight washer, 2 thrust bearings and the 93-95 counter weight.



I would really love to get a 93-95 front side housing and run a 93-95 oil pump also. And maybe a 93-95 intake manifold. But my budget is spread a bit thin right now.. https://www.nopistons.com/forums/pub..._DIR#>/dry.gif



Damn I want a 13B-REW Maybe next time......



Thanks for the info guys!!
