1. Basic Refresh: If your RX-7 is in relatively good condition and you are only looking to refresh the engine and replace some worn parts, this might include tasks like replacing seals and gaskets, rebuilding the carburetor or fuel injection system, and general maintenance. The cost for a basic refresh can range from $2,500 to $5,000.
2. Major Overhaul: This involves a more extensive teardown of the engine, including replacing major components such as the rotors, housings, and seals. Other tasks might include machining the engine components, balancing the rotors, and upgrading certain parts for better performance. A major overhaul can range in cost from $6,000 to $10,000.
3. Full Rebuild: This is a comprehensive process that involves disassembling the entire engine and restoring it to its original specifications or even better. It includes replacing all worn parts, machining surfaces, and potentially upgrading components for performance gains. A full rebuild can cost anywhere from $10,000 to $15,000 or more, depending on the extent of work involved and the quality of parts used.
4. Performance Build: If you are aiming to build a high-performance RX-7, you might opt for aftermarket upgrades such as a turbocharger, upgraded fuel system, performance suspension, and other modifications. This can significantly increase the cost of rebuilding, potentially ranging from $15,000 to $25,000 or more.
It's important to factor in the cost of parts, labor (if you're not doing the work yourself), any necessary tools or equipment, and potential unforeseen issues or complications that might arise during the rebuild process. Additionally, regional variations and the availability of used or refurbished parts can affect the overall cost.
It's always a good idea to consult with experienced mechanics or rotary engine specialists to get accurate estimates and quotes based on your specific requirements and the condition of your RX-7.
