The Rebuilding Process on the Mazda Rx 7 Rotary Engine
Each rebuilt mazda rotary engine has been completely disassembled and meticulously cleaned prior to the remanufacturing process. Numerous machining processes are performed as allowed by Mazda Factory OEM specifications. The compression, oil and coolant seals in addition to all the springs and o-rings for these seals are replaced with Brand New Mazda OEM seals. A brand new oil pump is installed as well as the timing cover. The balance of the gaskets and seals required to complete your installation are also included. We can also install a resurfaced flywheel for a small additional charge.
A 2-Year/24,000 Mile Manufacturers Limited Warranty is also included.

Upgrades and Additional Information
 We offer many upgrades to all of our Rotary designs. For an additional charge we can use brand new Rotor Housings on most of our Rebuilt Rotary Engines. We also offer Stage 1 and Stage 2 porting to give you that extra boost you're looking for. All of our Turbo Rotary Engines come upgraded with 3mm Apex seals and all non-turbo engines can be upgraded for an extra charge as well.

 From time to time we can also get our hands on some turn-key JDM Rotary Engines direct from Japan!!! Give us a call today and see what Gearhead has for you!!
