To all,
Now that Mazda is no longer supporting pre-86 engine internals what is everyone doing for things like rotor housings and such? I've read some posts about re-chroming and ceramic plating used housings, but the results seem to be hit and miss.

Build an 86+ engine to suit your application? There was nothing in the older engines that wasnt improved upon later, and no real reason not to do a relatively minor swap.

 

anyway, aside from that, it seems that some people who were in the loop (and had the resources and foresight) bought housings and are selling them now, so you can get "new" housings - just not sure for how much longer.

i'd like to agree and to an extent, i do, but what about the very, very few that are looking for a true restoration? i'd love to get a '79 and restore it someday and i'm about as anti-stock (in philosophy) as they come, so i can't be the only one thinking about this.

 

To all,
One of the main reasons why this won't be practical for alot of people are emissions regulations. Even out in Arizona, where I normally live, the only way to swap a 13B for a 12A is to do a complete install with all emissions and computer, etc. For those outside of this, in more smog permissive places, a 13B swap would be a good idea. Of course, the next question is when will Mazda stop supporting the 86-92 13B crowd? After all, the newest of those motors is already 14 years old.
Cheers,

i recently started to wonder the same thing, but i resigned myself to prepare by buying as many new housings as i can whenever budget allows.

 

It's sad but some day RX-7 will be rare and expensive. NEW engine parts even more so. I am just glad I have 2 new GSL-SE rotor housings sitting in my garage. Soon I will be looking for a prestine 88 GTU to put those housings into and hopefully drive till all the gas on this planet is used up.

 

Many states give emissions exemptions for really old cars, so once the parts supply runs out, you can maybe do the 13B swap and not worry about it. Or, make it emissions legal with a stock ECU and plumbing. If you've got a donor car, why not...
