Rather than rebuild an engine with questionable housings, I prefer not to rebuild them at all unless new or like new housings can be used. Studs are less prone to stretching under high boost applications. This combo seems to be more impervious to heat and dirt, so I feel it makes for a cleaner looking engine bay after a little time has passed. Rotary Engine Rebuilds We rebuild rotary engines in stock form as well as high horsepower performance engines. This means that the main components are not destroyed or worn beyond reuse. The eccentric shaft end play it set, the front hub is installed and the front main bolt is torqued.
Then you need to secure it to a pallet and wrap it to protect it from the elements. The improved air-flow increases top-end power dramatically with a noticeable power-band peaking around 8,000rpm while drivability, smoothness and fuel efficiency is reduced drastically. Rather than just tacking on the price of two brand-new rotor housings to the base price of the engine, we have a different philosophy. Due to some of the unique and proprietary parts and services we offer, much of what we do is considered to be quite unique and uncommon within the industry. Then today I learned how to rebuild a Rotary engine. We will also be expanding the number of stock Mazda parts and adding other products. The stationary gears will also be good reused parts.

The base price of the engine includes two good usable rotor housings. A master kit includes all the O-rings necessary to rebuild the engine along with all of the external gaskets. This is mainly because your core, or most any core you could find, would produce some poor housings with much wear on them. Please contact us for pricing. If a core is unavailable,core charge will be added to the engine build. Any rotor bearings or main bearings which are determined to need replacing will also be installed as a standard.
Example: Lets say you want to order a customized race engine and the needs are a four-port turbo block with non-turbo internals. If you are working with a specific time frame, please for more precise estimates. Within this same engine example, we have demonstrated that you require high compression non-turbo rotors for naturally aspirated use. Rotaryheads is here to service your rotary problems. We are in the process of transferring all the products from the old store, so it may be a while before you see all the products appear.
