This is a quick rundown on how one would go about rebuilding a Mazda rotary engine. This particular engine is a 12A from a S3 RX7 after the front rotor lost compression due to chrome peel and a cracked apex seal. This engine is rebuilt with near new housings and all new seals etc. No fancy tools here, this was completed at home with basic tools commonplace in most workshops. The parts needed for this particular engine were sourced from Atkins Rotary.

Very nice video. Makes me wish I didn't spend the $25 on the atkins rebuild video last month. What's the difference between hylomar and the other gasket stuff? I only had enough money for the hylomar lol

That looks like a new rotor housing there, where did you find one? Things are NLA everywhere I look

I've seen a couple NOS housings pop up on Facebook from time to time. - paying an arm and a leg for 12a stuff though. There's also Riggs rotary in Canada who sources alot of parts and resells them
