To try and help this thread redeem itself from the stench of homosexuality it has here is some tech info http://www.hangar18fabrication.com/blowthru.html

Use an old Subie turbo carb, if they're blow through. I don't know, because it's old and it's a Subaru, and I don't feel like researching ---- for you.

To the OP, you do realize that most NA built rotaries use "carbon" apex seals right? You do know why carbon apex seals arent used in boosted rotaries? They crack if boost even looks at them funny.

Does your "race prepped" engine have carbon apex seals that will eventually find their way thru your exhaust

the 13th round

if this douche knows so much about "race" motors, why cant he figure this ---- out himself. hang yourself, dont ask for advice then act like you already know what the hell your talking about. ask, then shut the ---- up and learn.

12a's suck *** in all aspects of rotaries. ---- a carbed 13b would be lots better. a full port isnt needed but other than better than stock apex seals its about the only thing you can do engine wise with a rotary. swap it out for a 13b and you will have much better luck with boost. definitly upgrade the spark system and make damn sure your carb is giving the motor enough oil. a rotary is just like a 2 stroke so it needs lots of oil. so here is your check list.

1. 13b
2. better apex seals.
3. upgraded ignition.
4. check out the carb before you even think about putting boost on it.

after all thats done a 60 trim t3 would do the trick. plenty of high rpm power and good driveability. if you decide to quit being a douche and listen to people trying to give you some good information you can learn alot. oh and as far as the ceramic apex seals cracking under boost goes, i have never used them, so i dont know. i have always gone to mazdatricks.com for the 8mm apex seals and they worked wonders on my last one. rotaries are just like dsm's in that they break down like clockwork if not taken care of so watch out. hondas are much cheaper and more reliable so i gave up the mazda.

Carbon Apex seals are completely different than Ceramic.

carbon seals= NA carbed rotary racing seals
ceramic = boosted injected seals

Generally thats what their used for. There's a local rotary guru named steve osley that gave me that info so im not 100% but he's built and tuned more rotaries than most ppl have even seen.
