Im all about these housing for lightness purposes but arent they made out of iron because its dispells heat quickly? wouldnt you be overworking our coolant system? How much is a set couldnt find it on the site...

When I called them about these a couple months ago, they would sell me the front and center iron.......but they didn't have the rear available yet.
I guess they have the rear one figure out now.
I believe it was roughly $4000-4500 US for the whole set without side ports milled into them.

Not to mention they would wear like mad. Stock irons are 60+ HRC hardness, aluminum is soft as hell and makes a **** poor wear surface. Now with some ceramic coating 
now that's a different story... Otherwise That $4000-$4500 would quickly becomes coffee table art. You better be makin some big money racing to justify spending that much on a "disposable" part or spend even more to have them coated with some slippery coating.

They are ceramet coated.
Cost is the only reason Mazda stopped using Aluminum in their production engines after the Cosmo Sport (first rotary). They still used aluminum side housings in there race engines.
Before ceramet coatings they used flame sprayed high carbon steel.

The aluminum sidehousings from the production Cosmo Sport 10A were used in factory racing 10A engines whether in a Cosmo Sport or the 10A powered R100 and RX-3s that were produced with the cast iron sidehousings.
If there was an advantage to using cast iron sidehousings they would have used them.

Just thought I'd chime in and mention that there's already a thread about these badboys from '03: https://www.rx7club.com/20b-forum-95/rb-aluminum-side-plates-238179/

I've been dreaming about those forever.
No turbo oil feed passages. Couldn't be too hard to drill for one of those...now where did my Makita go?
What I would be worried about is the strength of the dowell areas. They look to be about as thick as S5-S6 housings. Perhaps they were intended for non-turbo/low hp cars.
I hope ErnieT will be the Guinea Pig.

I can happily say that I'll be purchasing them with in the next year, if avaliable... I 've been drooling over those and other new ceramic advances with full doweling for years... I'll bee contacting racingbeat soon to see if any are avaliable,and to make sure mid-plate can be milled to except roller bearing/2piece eccentric Have plans for a future motor build...wicked kiwi-re short block 4 rotor all plates aluminum, full doweling, dry-sump, ceramics 30+psi yadaayadda... basically my midlife crisis motor build with a 50g price tag.... these toy's are what have driven me to succeed/ make money piles of it... now just feeding the priorities.. in due time....
