23a 4 rotor but what now.

Well I picked up a 23a 4 rotor kit. Its a jeff bruce kit brand new never ran for a pretty good price.
I know that there is only a handful of 12a based 4 rotors in the world and scoot sports fd was pretty impressive.
There is another fd in the states here that has a side port 23a but I fully plan on a full p port since there should be plenty of torque for street-able drive-ability.

Im not sure if I want to run Na full balance and clearance d setup for 12k redline or run a 10k redline with a large turbo and push for a 1000+hp monster and put it into my rx3 or first gen rx7.


I have also debated on selling the thing to finish the 20b in the rx7.

Got any pictures of the ole' 4 rotor setup? I've never seen, much less heard of a 23A.....

You could always play around with this for a few years.....then if it gets boring do the turbo setup....? Personally, i think it would be insane in either the FB or the RX3. When i think about a pretty serious swap, now that these cars are getting REALLY old, availability of replacement parts always seems to stay on my mind.

Best advice i could give is just take your time. Maybe after a period of time the right decision will present itself....

Could you measure the total shaft length for me? My 20B is out of the engine bay right now so I would like to see if there is enough room for the shorter 12a based 4 rotor. My 20b is moved back so if I could still fit this in the same spot without moving my rack would be a plus on a potential future project.

Its not much longer. I have my 20b moved back in my fd and it will fit just fine. I compared the two lengths when I first picked it up and I want to say it was only like 60mm longer. I will have to go recheck for ya.
This is for sale in case your interested.

Damn buying something like this is bad timming for me right now. I was originally planning on buying a kit sometime next year. Thx for the measurments. I just remembered that I had a bunch of 12A parts I can stack and set in the engine bay to get a better idea on fitment.

The mods I did to my engine are priceless. But in all seriousness, I would prefer a 13b based kit because then I could resuse alot of my already modified 20b parts to save time and cost.

I agree but then it starts to get long and harder to swap into something small like a rx3 or repu. And this motor is just plain rare.
I prefer the sound and look of a 20b myself. Even though the scoot sports fd sounds amazing!
This is for sale in the 20b section and race parts section.
