Compression first
A proper rotary compression test is one of the most useful filters before emotion takes over.
01 / KNOW THE CAR
Look past
the badge.
Mazda’s December 1998 release describes the revised FD RX-7 with a 280 PS rotary engine, while the final Spirit R series was sold only in Japan in a 1,500-unit run.
Heat and hoses matter
Cooling condition, vacuum plumbing, sequential turbo control, oiling and evidence of careful servicing all deserve attention.
Stock versus modified
Modified FDs can be superb, but calibration, heat management and parts quality need to make sense as a system.
Understand the final editions
Spirit R, Bathurst and other late variants carry their own equipment and value signals. Verify the actual car, not a badge added later.
