Re-chromed rotor housings
There is a long thread on the other forum
![]() Anyway, we'll start one here. Below are pics of the first housing we had done and then the second done so you can see the improvement. Right now we are working on fixtures to be able to do them in production form as a matched pair of housings. At the same time we are making the necessary parts for chroming 12A housings as there will be an immediate demand for 12A as you can no longer buy new ones. 6 FD housing are ready and waiting too. We have the housings pictured below in a running engine for a couple of years now so all looks good so far. ![]() ![]() ![]() ![]() And the second one done: It's the same shot getting progressively brighter. This is the final and how we want them to look. ![]() ![]() ![]()

OMG its about time! I knew savnig old housings would pay off. Will you have the info about the limitations of what can be re-chromed?

Right now we are only able to re-chrome housings with no damage to the steel insert. Later on we plan on developing a method of repairing the steel insert so even damaged housings could be done.
Material used is top quality hard chrome duplicating the factory finish as close as possible.

Looks great man.
This is what we need, I'm tired of cnc'ing 13B housings to 12A size. Would you be able to rechrome MFR rotorhousings too ? Kim - Lost member of the RX7club. |

We're looking at MFR housings as well and my guy tells me they should be no problem, just have to deal with them a bit differently with no steel insert.

Good stuff! What do you think this treatment would cost?

At this point I'm not too worried about pricing for resale, it will be good. There are always ways to bring down production costs. Besides we need to get everything set-up first and do a pile of testing in some race cars.

Although it's early in the process and I assume you can only venture a tentative statement, how will the pricing compare to your ceramic coating?

hmm your saying that the steel insert damage is the only thing you cannot fix so reseeding chromium is not a problem what about mild scratches around exhaust ports . define extent of damage ?

That's right for now we cannot repair the steel insert but that will be looked into after we finish the required fixture for production chroming. Scratches are no problem as long as they do not extend into the steel insert and cause it damage. In other words if the chrome is removed there can be no damage to the steel insert because it would have to be repaired before re-applying the chrome. Any existing damage however mild would only be accentuated by the chrome.
