does any one know if renisis rotors are avalible where to find them and will they fit 86/88 n/a engines

 

www.mazdatrix.com click on the rx8 section. I am not sure about fitment though.

 

from talking to mazdacomp, the renisis rotors are almost half an inch narrower than the earlier 13b's

 

LOL...if they were 1/2" narrower, wouldn't it be a 12A?

 

WHAT???
Gimme some of that crack you're smoking!

People on nopistons have already built 13B's using rensis rotors in them. One guy built a PPort motor using them

They fit fine,k however you have to have the apex seal grove modified to fit the 13B style apex seals if you want to use them because renisis seals are shorter. Once you do that you have to use 13B corner seals also

And the new seal that the renisiss has (something to do with exhaust) on the rotor the people on nopision's didnt use, its only there because the renisis side port exhaust

Mazdatrix has the rotors for sale, and there less than S5 n/a rotors

thanks a lot guys

 

They are the same. Dimentionally.

 

thats what they said when i talked to mazdacomp, they said the apex seal was 1/2 inch narrower and thats why i couldnt use the seals in replacement for the 13b seals that they were out of at the time. both the salesguy and myself just assumed the rotors were smaller also.

i'd say there's a difference. guess thats how it is when your car is actually in production and not over a decade old and mostly forgotten.

 

shoot this makes me wana blow my engine ang go with CHEAPER!!!!!! renesis rotors. WTF????

oh well i guess they are finaly delivering on cheaper parts. only took 15 years........

 

AMEN TO THAT!!! my engine runs decent but i think i could with stand a rebuild for more power.(n/a that is)

 

not to mention the rotor are lighter

 

did they say what kinda power they got with the new rotors? how much gain?

 

What would be the benefit of using them? Aside from price..

 

compression ratio is 10.1 verses ours

 

i would say a street ported,and a decent exhaust set-up would make good power with these rotors and could only get better from there( stand alone ecu,injectors ect.)

 

ah well, atleast we all can look forward to putting renisis rotors into our rebuilds when we blow our engines up for that price.

 

does the renesis counter weight swap out too? you gota have that also to make the engine run right.

 

Yeah, you've got to mill them for the taller seals to run them. Someone tried using the renn seals and they started warping after one race from the PP exhaust. the power increase was something like 20 hp on the PP.

 

I hurd both the same things


As for the CW's, i was told to use s5 or 3rd gen CW's

 

^^^^^ but both s5 and fd have heavier rotating assemblies. how can that be?

 

i'm with you. renisis rotors are lighter

 

search for post under username "mazdatrix" infos are a little old , but it should answer your question
