Might have to get some of this information together to keep track of them all.

Trying to find out what mine is, but I think it may be a new Mazda one as it has no numbers at all.

See what I can find when I'm in front of it.

 

There is already a thread on this, check the archive.

 

499 here, but it's a rebuild. No idea by who. There's paint pen markings all over the housings/irons. No stepped dowels. Where on the E-Shaft would I find the number?

 

I am the proud owner of D456, not installed in a car yet.
I haven't opend it up yet, buy a camera inspection through the sparkplug holes revealed a rusty rear rotor. So it will require a overhaul in the future

 

Got my 20B few weeks back, Mazda reman B882, open it it up, everything is mint inside, bearings looked mint, no step wear, mint housings.

Will be built with a S4 T2 Balanced, lightened, clearenced rotating assembly, large street port, 4 oversized thru bolts.

 

# 567 for me.

Came with a car I purchased I think it's been apart before as all the irons are painted.

I think Banzai or Pettit built it many years ago, but porting is stock, no idea what's inside we will see if it holds together on the dyno in spring!

 

I picked up a 3 rotor two years ago. She is # B300.

 

Wow, I totally forgot about this thread...
I have D659 in my FD, and I imported a Cosmo, so I also have C329.

 

My 20B is marked C927. The 20B insignia has black paint around it with the 20B raised numbers unpainted.

Just opened her up...will need a rebuild.

 

C328

 

#743 no letter

 

Importing from Japan.

 

This thread goes way back. I still have my ‘preserved’ 20B. All three rotor housings are stamped

Stamped rotor housings. C927. However, there is supposedly another ‘engine #’ somewhere I’ve never found.

 

Happy to join the group. Just got B526.


Had a stuck side and corner seal from loads of carbon buildup, but otherwise is pretty minty inside.
