20B N/A with RX8 rotors??
 

Well, I was just told that all my parts are cleaned and ready to be assembled..

But now I'm thinking.. Maybe I should go with 20B N/A??? Do anyone know if RX8 rotors could be used?? I think I've heard that you could use the RX8 rotors...

I'm now thinking about going old school and go 20B N/A Carb'd!

take to Logan with defined auto works in southern ohio. His FD is N/A and 20B and to the tune of 300hp

I've seen his work and talked to the guy who helped put it together...But his is EFI NA.. I believe. My guy is whom I trust and knows quite a bit about carb... he's just not sure about Renesis rotors as he hasn't taken one apart.. i'm thinking about bringing him one this weekend to take apart and compare the rotors.

I'm also waiting to hear back from Carlos Lopez. He and I talked about this before as my builder wanted to go NA/Carb 20B... now I'm thinking it might be easier and unique...

This is the picture Carlos sent me about a year ago.. I think this is the set up I'm now considering...

My only concern with Renesis rotors is that they aren't designed to handle peripheral exhaust ports, so I have no idea how long the lighter/shorter apex seals will survive.

I bet Landers could prob. give you a pretty good idea whether or not they would work.

ahh... I didn't think about that... Hmmm..

Aren't you supposed to machine the rotors to use standard 13B/20B apex seals?
EDIT: Just searched evil forum and I guess it's not necessary, but I did see that the standard renesis seals warped too much on the peripheral exhaust ports so ceramics had to be used. I think if I were doing it, I'd use 13B seals. Also, the thread I saw was from 2004, so things may have changed.

I'm interested in seeing more input on this.

Yes you can use the rx8 rotors in an na 20b. The place i will only trust to do the rx8 rotors and has done them on numerous times. Is Roan At xtreme rotaries in Au. Trust me.. well worth the money.

Do not have shops around the state do your rotors and balance. Its a joke. Trust me, Been there done that. I'm not going mention names not that type of person.

Also the rx8 rotors will be machined to except the 13b style apex seals 2mm or 3mm.

Good luck with your project...

Is that a 20b with renesis housings? I never gave that any thought.

how where do you get a dizzy for a carbed 20b i was told on the evil site cant be done heck id do that any day for my sa.

yes it is

only issue i heard with that is the one exhaust port. and i think intake port is smaller than the others...

what would you guys use for carbs then ?
