It's a waste of cash to get them refinished if the chrome is still smooth.
But..
If you do have damaged chrome, and your still talking about REC. They do offer a Cermet coating. It's not all that cheap either tho, and it's brittle.
I still think that the rechrome process that Goopy offers is better for the cash spent.

My motor is currently complete and running, but I was thinking acquiring another set of housings to have resurfaced, and building a different motor with cryo apex seals, and upgraded gears and bearings, building a 8-9k rpm motor. I read about the cermet/ceramic coatings, on the rotors, irons and housings, i dont think i need that, I just want to build a really well built street motor. Im new to rotary, I know a lot about the rotary, but this is my first, all advice is greatly appreciated

This is my first build as well, but I have gathered a ton of awesome information!! Most of it came from Rob at pineapple racing. That guy is awesome!
But if your just gonna build a spare mill. I suggest finding one, and stripping it down before ordering parts you won't need.
I did the same thing.
Choose your performance level, and what you want to expect.
Then you can figure out a budget, and the parts you'll need as you go.

the only other option is a 13B housing that has been cut down to 12A size and had the coolant seal lands cut in. Atkins sells them but they aren't much cheaper than Goopy with the rechroming. in fact i think they were slightly more expensive.
of course if you go that route you must use a matched pair of housings, since the exhaust ports will be 13B proportionally sized.

I have 2 used housing in decent shape on the back burner that a member on here is hooking me up with. I'll keep the one for a spare should I have an oopsy.

If I was building a race motor I'd probably go that route.
I haven't heard to much about those milled housings tho??

though seems they are out of stock, not sure if they plan to make more.
if you are interested i can see what i have in 12A housings, depending on how cheap though.... i don't give away my inventory, we all gotta eat.

But I actually have a pair of good housings coming.
Sawyer10702 might be interested in your offer tho, if you have some up for grabs?

it's been reduced to 5 now so ur good. and lame it's not. we want people that will be active members of the forum not for those that have no interest in the cars and just want to sell off parts or car that they inherited some how. this is a place rotary enthusiasts and to find technical advice first, that just so happens to have a classifieds section. if all someone wants to do is unload parts or a car, hit up craigslist, we don't want u here.

The bit about "if all someone wants to do is unload parts or a car, hit up craigslist, we don't want u here" I find funny though, because I do want a newb to list their car and parts here so I can scoop up good deals from misinformed people

sawyer10702 did PM me asking to buy some rotor housings. Unfortunately, the ones I have for sale are early 12A and will not work on a first gen RX-7. He's just looking for parts.
There are some other valid reasons for having a post count before buying/selling. Before the post count rule was put into place, I would get a lot of zero post users asking to buy parts. Once I responded, I would never hear from them again. It still happens, but not as frequent as before. I will not sell to ANY zero post user. I ask them to get 10 post first.

well, not everyone feels they have much to contribute though. it happens infrequently that someone just stalks the forum but may have some usable parts for others.

I personally love this forum!
Even tho I'm not running an RX7 I have gathered a ton of good info toward my swap. Lots of good people on here willing to help out a fellow gear head. I wouldn't let the minor details wreck a good thing.

wasn't aware fel pro started making the housing seals, i have no experience with it though. i checked and verified that it does appear they do now have a full gasket kit though, not sure why they waited this long to do so... the sales are already way low now versus decades ago.
however, for not much more i would go with the atkins set, they use OEM bits in theirs.
could be atkins or OEM is selling them through felpro now(not sure if they do that sort of thing or not), but their picture stinks so i couldn't tell ya. nippon reinz also now sells replica seals.

They offer different levels of kits depending on what you need. I find the prices pretty decent.

You still need apex seals but that's where Atkins come into play.
