9 Years Of Rotary Building Experience.
Welcome to The Rotary Doctor ! We specialize in Mazda Rx7 rebuilt rotary engines. Don't be fooled by other rotary engine builders. We have taken most of them apart at one time or another and were surprised at the poor quality in parts used...

We build one rotary engine at a time! Each rebuilt rotary engine is built with the same amount of attention. We offer stage 1, stage 2, stage 3 or stage 4 rebuilt rotary engines. Every rebuilt rotary engine is built by Dan Atkins only!

We won’t claim to be the biggest Rotary Engine builder, however we will claim to have one of the Best Rotary Engine builders in the US, and you won't find better customer service!!

We use New Apex Seals in ALL our Engines!!
