I posted this at the RA thread but decided to post it here to keep it separately:

"BTW, there are two other friends I know that are currently using RX-8 seals. They are a 2-piece thinner design with longer springs. One of them is a racing drag car that I personally saw it dynoing 647 whp with a lot more than 10 passes. They have not blew/chk them yet but have not reported any problems. The other one tried them in an FD and blown them while tuning the car. So it looks to me like is a good seal if the ECU is WELL programmed/tuned. I will probably go with the RX-8s next if something goes wrong with the RAs. I will let you informed about my car (FD3S) and everything else."

Has anyone tried the RX-8s?

 

bad idea with PP exhaust.

 

What do you mean? Have heard any bad experience?

 

I think what he is trying to say is that the thinner apex seals will arc a little and hit the lip of the exhaust p-port. This isn't a problem with the renesis because the exhaust ports are on the side.

 

Actually yes, this has been proven. Mazdatrix found this to be true. They bend when crossing the peripheral exhaust port.

 

so no good?

 

I wouldn't trust information unless I have personally seen the seals go in.

Also aren't the Rx8 seals like thinner than the normal 2mm seal? If so they would have too much side clearance.
