I specialize in all Mazda 13B and 12A wankel rotary engines.

The duration of an engine rebuild varies depending on the scope of work. I also work a full time engineering job so I usualy only do a handful of builds each year. I try to take my time with each one. With the rotary engine, patience and attention to detail is rewarded with good compression. Most basic rebuilds are completed in about a month. Porting, specialty parts, or replacement of major components usually adds a few weeks to each job.

Due to the complex maintenance requirements and possible racing applications of these engines, I do not offer a warranty on any parts, services or rebuilds.

I currently do not have a shop that is open to the public. I am by appointment only as I work out of my home garage. Because of this, it is preferred to bring just the engine short block, stripped of all accessories for rebuilds. Please see the contact page to discuss your build.

Please strip the engine as much as possible. All accessories such as alternator, water pump, A/C systems, wiring, gaskets, etc. should be removed from the engine. As close to a bare short block as possible. This makes the rebuild process more streamlined for me, and the car owner will have a better idea of how and where things came off as these items vary from car to car. I cannot be responsible for accessory items that I cannot test, or external consumable items (gaskets, O-Rings) that may have been lost during transport or teardown. 

Do not remove the front hub bolt (holding crank pulley) and leave the flywheel attached. You may remove the clutch.

Yes. A deposit of $1500 is taken at engine drop off. The rest will be owed at pickup. An estimate will be given for the rebuild at drop off but is subject to change if engine internals are damaged or worn and need replaced. Customer will be contacted after teardown to discuss engine condition and recomendations will be given if necessary.
