anyone has an rx2 block thats in good condition
let me know
thanks.

 

Are you looking for the original twin dizzy setup or will any old 12A work for you?

 

I know of a original 1971 Crate motor with 0 miles in Tampa

heres the link

I think the seller is a member here, but I'm not sure.

 

I have a complete rx2 engine. It was dissasemmbled to check the internals which are all in excellent shape. The housings look like new and everything was suprisingly clean. All seals are in very usable condition. Let me know if your interested.

 

I have one that is still installed in my rx2 it starts and runs.

 

i have an old twin dizzy 6mm core motor, finding replacement 6mm seals might be a little tough to find though..

 

what are they worth? twin dizzy

 

finding a collector who wants to use the inferior motor? worth what someone is willing to pay for it. Jay Leno, the man with bucks didn't even feel like running his original 10A cosmo engine because they really do not last.

 

thanks. i have 12a twin diz.

 

same boat, the old engines just didn't last but do have a fair amount of collector value in my opinion. but how much a good condition running old school motor is worth is up to the market to decide. everything is only worth what someone is willing to spend.

someone who wants an engine comprised of 95% discontinued parts is stuck with the very very few left out there still in running condition.

 

cool. Great info

 

I am allways after early twin dizzy internal and ext parts and items.Only engine related.

 

I have one great (almost perfect) rotor housing and one that in my mind could be used but there is a eat out spot at the bottom of the housing (effects apex seal surface). Open to offers.

 

the rotor housings in near perfect condition aren't really worth a whole lot IMO. the chrome is too thin for use in later model hard seal 3mm 12A engines. the housings are almost always in great shape due to the carbon seals that the engines ran.

the only compromise that i could see using the older rotor housings would be either to have the 6mm carbons duplicated or run ceramics. i'm considering rebuilding this engine and fabricating a set of ceramic seals for it, maybe a collector would be interested down the road but who knows..

still needs to be bead blasted but for now the parts are just going to be display pieces.

 

I have a complete twin dizzy 12A. I also have 2 NOS 12A rotor housing and a bunch of near perfect old school 12A housings.

 

does it still spin?

the original irons had a tendency to rust, even when not subjected to direct water.

 

It spins great and has compression. I have not tested it with a compression tester though. I got it, and a bunch of other NOS parts from a gentalman that use to race an RX-3. I have a bunch of carbon 6mm rotor seals and other NOS parts. I even have some engine rotors that have double side seals.

 

Just saw on JNC in the Mazda swap meet, a twin dizzy 12a and 4 speed, complete for $450. In WA state. Just sayin...

 

Thats a fair price. My also has a 4 speed and I'd sell it all for that price.

 

cool, i used to see the 6mm seals pop up now and then but not in recent years. i also have a local friend who has a set but he won't let go of them..

sounds like you have something to restore it with, i wouldn't trust the original seals to hold up though currently in the engine. even then the engines had a hard time making it past 30k miles before the seals would start to rapidly deteriorate, get stuck from carbon or blow out under light detonation from a poorly kept fuel system.

a local guy also had a ton of old school 12A parts, i contacted him about buying the 12A housings until i remembered he mainly had the old 6mm engine parts so i passed on the lot.

unfortunately there doesn't seem to be a lot of interest in the nostalgia of these old engines due to their unreliability. but it's cool to see the NOS stuff still floating around.

 

I have a pair of 73 rx2 couPe rotors with 3 good 6mm carbon apex seals the other 3 are stuck on one of the rotors I have these laying somewhere in good shape

 

i also want to know where all the rotor #2 plates went! i only ever see #1 still on the housings.

 

There is no #2 plaque. I've seen motors that have 2 #1 plaque housings, I've seen some that have no plaques.

 

I have a complete 12a twin dizzy from a 72 Rx2. It would start and run if I needed it to. I tried to sell it a few times, but now decided to clean it up real nice and make it a display piece. It's a real piece of history and that's hard to come by in the rotary world.

 

THere is a Brand new one on Craiglist of Orlando, 1873 Rotary Engine dual, they want 2500
