13b-re 2 rotor cosmo engine for sale

Recommended Posts

$950 with everything shown below. I also have a couple of turbo 2 transmissions to go with it, if you want to buy those (pick up both for $150)


Bought this from a japanese importer about 5-6 years ago. Has never been used (by me) except being stuffed in and out of a datsun 240z about a dozen times. Block shows signs of being previously rebuilt in Japan (silicon beading, etc). Never had power to test compression, but when spun by hand it seems to build compression pretty well, and lots of (air) resistance on the stroke. Motor has been turned by hand every couple of months. Looked like this in my car:




You can find all the info about the swap in "Other Engines" forum, by searching for "auxilary"


Front engine cover and oilpan have been converted to 13b gsl-se to allow front mounting, oil pickup has been relocated, and there's a new front engine cover seal. New chain on oil pump. OMP has blocked off, and front engine cover and has -10AN adapter installed for oil cooling. I should have stock oilpan and engine cover , in case anyone wants those.


Waterpump is new, water pump housing is from an S4, and thermostat housing is from a 12a, I think.








I also have -6an modified fuel rails (to be run in parallel) for this motor:





(tig welded by 73botiz)



Should have almost all matching gaskets here as well for it, they are included with the block (these were not cheap, all mazda OEM units purchased through mazdatrix). oil seals included (see upper right)




Local pickup only - SF Bay Area, California. I have a cherry picker, so bring a truck. I even have an old pallet I can put it on, and I will throw in the pineapple racing engine stand adapter with it.


PM me if you're interested

Someone *cough*owen*cough* should buy this.


To match this, for a Z you can also get the fully built exhaust (3", straight through dual mufflers). mid muffler is a magnaflow SS bullet, end is a magnaflow muffler, straight through true 3". 4" exhaust tip. Downpipe is SS, 3" with 2 O2 sensor bungs with plugs (for tuning) anda port for wastegate dump (vband). All exhaust bits feature vband clamps (SS). $450 for the exhaust with downpipe, and it's a direct bolt up to S30.









Pic of it mounted on the car. It will clear stock gas tank too

It was 90% complete, but I aborted the project for personal reasons. They weren't financial or component related. If you want to see pics, you can check out www.rotaryz.com for some of the progress I kept updated. I sold off the rotary mounts, but they're not too hard to fabricate. Use an FB GSL-SE front engine mount and modify the stock s30 crossmember to bolt/weld it to, the transmission mount can use the stock tranny crossmember, just drill out the main pilot hole to bigger diameter.


here's an old thread when i was doing the swap.




you should buy this and the exhaust - all the hard work is done! :)

I have a FC in need of a rebuild right now.


Plz get compression nums on all (6) faces,

~90's mean it's in need of a rebuild. I've

done RE and 20b swaps in my FC, this would

be a nice one for the roller I just picked

up. Gimme a call at 206-fourtwenty-9564


You can use these for transaction history,
