Nice. Yeah all the little crap is worth doing with a new motor and it adds up quick - coolant hoses, OMP lines, various bolts, nuts, and studs, etc. etc. etc.
When I install an engine I don't want to have to go back in there any time soon, get it all done right with good, new gaskets and hoses and you don't have to worry.

I'd get a spare (with all the trimmings) if I had the money or the space.

I really hope they keep this up, this is a HUGE boon to the community.
Having an RX-8 now I can really appreciate the new FD motors. RX-8 remans are about $4000 and you need to return a core and it's a total crapshoot as to what you get - mix of old and new parts, some maybe worn past spec, maybe used seals, who knows.

currently they have a whole Rotary engine factory that is tooled up to make Rx8, FC and FD engines, so that is what they are doing. When they retool the factory to make something else, that will be it.

i just checked, just now, and its $9872..... the part number is in the parts catalog, but most people assume its NLA or something, also Mazda USA won't carry it so you need a vendor which doesn't buy from Mazda USA

That's good to hear. I felt bad thinking people were cannibalizing JC Cosmos for their 20Bs over there.

i now only build CPR motors from new blocks and do a 6 page spec sheet on them prior to doing my thing with them on the rebuild. i have found all of them beautifully machined without exception. there is a paint dot on every piece down to the tiny screws pinning the bearings!
the one item that apparently can't be machined to spec is cornerseal to sideseal clearance. i am quite sure a non-machine---that'd be human---does it. quite sure, because clearance is all over the place. the last motor i did had one side seal at .017! i generally find half of the SS are clearanced more than .007. clearance should be approx .002.
i had to use two feeler gauges as i didn't have anything larger than .015 in my rotor feeler gauge tray;
other than that, the new blocks are beautiful. i am expecting delivery of a new block in two weeks for my FD which will be the first time i have had one in my RX7.

Sorry for posting anything related to AM, I didn’t realize they were such scum. I had a very similar situation with a dude named Brian Gray in Smithfield, NC. He destroyed my FD. I took him to court over it and got a $12,000 judgement placed against him. He skipped town, so I never got any of the judgement money.
