Atkins Rotary specializes in rebuilding Mazda Rx7 rotary engines, specifically 12A, 13B, and 20B Mazda Rx7 rotary engines. We also sell a wide variety of rx7 and rx8 rotary engine parts and accessories. We manufacture our own high quality aftermarket rotary parts, superchargers, and high performance supercharger pulleys, as well as carry all of Mazda's engine parts. We limit the use of used parts in our rotary rebuilt engines, in order to provide our customers with the best Mazda rx7 rotary engine on the market at the best price. We take pride in the fact that our rebuilt rotary engines are of a higher quality than other remanufacturers because we scrutinize our specifications much more seriously and precisely than other shops! Our engine compression rates are typically higher than Mazda's rebuilt Rx7 rotary engine standards and we pressure test every rebuilt rotary engine to ensure that our coolant system is in tact. We offer a two year 24,000 mile warranty on all of our Mazda rebuilt rotary engines, and have had very few returns. We make many of our own parts including but not limited to: apex seals, thermal pellets, solid corner seals, high performance pulleys, intake manifolds, exhaust flanges and superchargers, all of which have been tried and tested by David Atkins and his professional championship winning racing career. Raymond Tossas at New Import Speed Shop has been using Atkins Rotary apex seals, solid corner seals, and viton oil control rings among our other rotary parts in his rotary car and is currently running a 7.46 quarter mile time.
