I've heard that rumor also about the matched rotors and e shaft. I *think* I heard it from Dragon

 

judge ito told me as long as the rotating assembly was a matched unit from mazda its fine to rev to 10k! i rev mine up to its 10.5K rpm redline and its fine [/quote]

i never saw a redline at 10.5k on my dashboard.......... must be vosko spec meters

 

what does matched rotors mean?

my redline is set on my haltech! the tach only goes to 9k but the needle keeps going LOL



i used to rev the crap out of my T2 also

 

matched meaning came from the same engine from mazda

 

So essentially you're saying that if I used an FD shaft with Cosmo rotors (well just one) that I'm somewhat out of balance compared to the stock FD e-shaft and rotors?

 

possibly.........

 

so you guys are saying that i can reve my stock engine to 8k+ and its safe?

 

Ok, well I guess I stand corrected. But probably wouldn't hurt to have everything race prepped...balanced blue printed or whatever if you're going to do a rebuild and plan on reving to 9 or 10k.

 

yeah i think thats the safe way of doin it
