About our RX-7 Engine Rebuilds

    Rotary engines are unique when rebuilding. Many parts, after being  cleaned , very closely  inspected , and  measured , may be reused. Some must be discarded because they are not machinable, or  are just plain worn out.      It is relatively inexpensive to assemble a rotary engine with a lot of used parts, however success is only mediocre. An engine is only as good as its weakest link. An engine assembled with more new parts lasts  much longer and runs more efficiently.      At The Rotary Doctor, our engines are built to last several years and many miles with adequate maintenance. That is why all of our engines have  new  apex seals, corner seals, side seals,  Viton  oil control O-rings, and all springs are replaced. We also use only  new  front and rear oil seals, pilot shaft bearing and seal (for manual transmissions only), eccentric shaft replacement, thermal pellet, all internal coolant seals, gaskets and tension bolt o-rings. 

Engine Hard Parts (ALL ROTARY REBUILDS)

Most rotary engines lose compression on one rotor when they go bad. The apex seal wears thin and rolls out, destroying the rotor housing as well as the rotor itself. If you want new rotor housings, add $1,300.00.

1993-1995 Turbo Housings NEW, add $1,700.00+.

On most of the rebuilds we do, the customer wants us to remove and reinstall the engine. When we do this, we send the fuel injectors to RC Engineering for cleaning and balancing. Many times one of the fuel injectors will be leaking. The prices below include: oil filter, oil, antifreeze, distilled water and gaskets. Engine mounts oil injectors, hoses, belts, and oil lines are NOT included.
