Rebuild Kit
 
I'm starting my engine rebuilding but I'd rather do the work myself and learn more about the rotary engine than what i know now but I'm having somewhat of a difficulty finding a rebuild kit.

I live 15mins away from MazdaTrix but there kit is costly, are there other websites to buy the rebuild kit from?

Rebuild kits are always going to be a little costly, depending on what is included.

I use Atkins kits normally because they include everything, so it's pretty convenient.

Atkins Rotary - Rx7 | Rx8 | Mazda | Rotary | Engine | Parts

Also this may help:

These videos will help you in the process of rebuild a 13B or 12A engine. While they deal with an older 13B from an RX-5 Cosmo, the engine internals are basically the same for any 12A or 13B. The only real difference is that on engines newer than '85, the coolant o-rings are in the irons instead of the housings as shown in this video.

The first video is engine removal. While it is an RX-5 Cosmo, an car that few will ever see let alone work on, the process will give you the general idea of an engine removal. Steps are similar for most rotary vehicles, it's the details that differ.


The next video is engine disassembly and some cleaning. This is an old carbureted 13B so the accessories bolted to the engine are different than newer engines. However the process of externally disassembling any rotary is about the same. Covered here is also flywheel removal (same for any rotary) and engine parts cleaning.


Cleaning of all engine parts continues in this video. Provided here are examples of how this is accomplished with a minimum of tools and supplies. It's a lot of labor to clean old parts until they are looking new again. At the same time, parts should be inspected.


Finally, here is the engine assembly. This video includes clearancing side seals, assembling all the seals onto the rotor, then assembling all the parts into a 13B short block.

Cool, Thanks Aaron.
For about 1200 its not bad. I've been reading good reviews on Atkins. I'll definitely use them.

Just got done with a rebuild and used Atkins. All I needed was coolant seals but figured since I had it all apart I may as well do new apex seals and springs. I got the seal kit and apex seals and springs for about $480.00. You may not need to replace everything that the master rebuild kit includes.
